Thorlabs' LTC56 Series Kits are complete laser diode (LD) current and temperature controller sets including a laser diode mount, collimating optic, and accessories. Modulation of a laser diode is possible but not via the laser diode controller. Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. Thorlabs offers laser diode mounts for Ø3.8 mm, Ø5.6 mm, or Ø9 mm TO can packages. Higher current (5 and 20 A) and rack mount controllers are also available. The divergences are typically specified as "Beam Divergence (FWHM) - Parallel" and "Beam Divergence (FWHM) - Perpendicular" for the two axes of the chip. Thorlabs' Laser Diode Modules are available in either collimated or adjustable-focus varieties and provide output powers ranging from 0.85 mW to 4.5 mW (laser safety Class 2, 3R, or 3B depending on the model). To calculate the beam size of a collimated laser diode, we first need to know its divergences. The top surface has heat sink fins and a recessed region to mount the laser diode, resulting in a low profile package with a temperature coefficient of 3 °C/W. 2 to the right). Warning: The RF input is directly coupled to the laser diode. If so, are there disadvantages relative to the more expensive LDC202C? The correct distance between the laser diode and lens can be achieved by adjusting both the S05TM08 and the SM1A6T adapters. They include the LDC205C LD Current Controller, TED200C Temperature Controller, LDM56(/M) Laser Diode Mount, and other items necessary for the stable and safe operation of standard Ø5.6 mm laser diodes. This 3.5X magnification can be achieived using the PS881-B Mounted Anamorphic Prism Pair. The pass through design allows le Laser Diode from Thorlabs is a FP type. Please note that the diameter of the lens must be larger than your desired major axis beam diameter. You should also be sure to make sure that this TEC can handle the heat generated by your diode. The LDM9T Laser Diode Mount has a standard 4-pin LD and PD mounting configuration. The pin layout of the style F connectors place the LD and PD next to each other, instead of across from each other as shown in Figure 3 and described below in detail. Note: Parallel and perpendicular notation are specified relative to the junction plane of the laser diode. See the Pin Configurations tab for more information on Style E compatibility and necessary modifications to the mount. All of these controllers operate in a similar manor. Many of our mounts include a TEC that supports temperature regulation of the housed laser diode, indicated by the thermometer symbol on the links below. For this application, the ideal lens is an -B AR-coated molded glass aspheric lens with focal length near 5.6 mm. I google it and found that the original price is $375 each. In addition, the laser diode can be easily overdriven by an RF voltage above the specified level in Eq. Threshold Current referenced on the attached data sheet is 30 mA with slope efficiency of 0.25. It is attached to ground and the 9 o'clock and 3 o'clock pins on the laser socket when the PD Polarity Switch is set to CG (cathode ground). Because of the variety of diode pin spacings we must ensure that any funnels put within the cold plate through hole will open wide enough at the top to ensure the diode pins are separated far enough from the can as to prevent damage. For larger translational adjustments, the CT1 1/2" Travel Translator can be used. Take care to ensure that the lens does not contact the laser diode. The style F pin configuration, though similar to the style D configuration in that it contains four pins, has a pin layout that prohibits use in the LDM9T mount. A power supply is included with the LDM9T. Take care when controlling and adjusting the RF voltage to avoid damage to the laser diode. From optomechanical components to telecom test instrumentation, Thorlabs' extensive manufacturing capabilities allow us to ship high quality, well priced components and devices for next-day delivery.

Software for Laser Diode Controllers. These pins are typically used to monitor LD voltage when used with the Thorlabs LDC series controllers. Style G laser diodes require modification to the laser diode mount. In style F connectors, the PD and LD pins are located diagonally from one another (9 and 12 o'clock positions, or any adjacent position). Please note the orientation of the laser diode configuration (top/bottom and front/back) as it may vary between manufacturers, product lines, and/or configurations. Integration into these multi-axis flexure mounts provides excellent control over a diode's position and alignment with optical systems. Next, check to see if the numerical aperture (NA) of the diode is smaller than the NA of the lenses so that the light emitted from the laser diode is not clipped by the lens: Figure 3. Cage rods can be attached directly to the front plate of the laser diode mount. Unmounted prisms may be used as well. If a third-party controller is used, see the laser diode connector pin configuration in the operating manual to determine the proper connections. The compact housing protects the pigtail from physical damage, while also offering excellent thermal characteristics.

This can be compensated for by inserting anamorphic prism pairs or cylindrical lenses into the collimated beam. Now I'm trying to figure out how to modify this mount to make it useful and to meet my project deadline. Solving the first equation again with your actual focal length and major axis divergence angle yields the actual major axis beam diameter, = 3.3 mm. If your application requires the higher voltages typically necessary for driving blue and other short laser diodes, consider our LDC202C, LDC205C, or LDC210C controller. The top surface In order to use the mount with any other laser diode style will require undoing the modification performed above. 2 thermistor A TEC power supply is included with the LDM9T. In the above schematics, LD denotes the laser diode, and are the beam diameters in the parallel and perpendicular orientations, respectively, and and are the divergence angles in the parallel and perpendicular orientations, respectively. Regards A schematic showing the internal circuitry of the laser diode is shown in Figure 4. The bypass is accessed through an SMA connector on the side of the mount, is directly coupled to the laser using a bias-tee network, and features a 50 Ω RF input that can accept an AC-coupled RF source up to 1 GHz. The LDM9T Laser Diode Mount is compatible with all Ø5.6 mm and Ø9 mm laser diodes with 3 pins in an A, B, or C style configuration as shown in figure 1. Thorlabs offers a versatile range of accessories for convenient integration of photodiodes and laser diodes into functional systems. Step by step procedures for mounting optics and controlling the laser diode are found in the manual and the Pin Configurations, Electronic Control and LD Collimation tabs above. This pin is connected to the 12 o'clock pin on the laser socket when the PD Polarity Switch is set to AG (anode ground). Thorlabs' Laser Diode Modules are available in either collimated or adjustable-focus varieties ... KM100 Kinematic Mount. The configuration shown to the right allows direct mounting of style A, B, C, D, and E configurations without any alteration to the mount. Because of this asymmetry in the two axes, an elliptical beam will form as the light diverges. I have no idea what they are for. For informational purposes, this is a copy of the website content at that time and is valid only for the stated product. Always mount the laser in a suitable heat sink to remove excess heat from the laser package. i.e. For more information, see the sections below or contact tech support. Thorlabs' HLD001 TEC stabilized laser mount is designed to integrate our Ø5.6 mm and Ø9 mm laser diodes into our multi-axis flexure platforms as well as provide temperature regulation for the diodes. The laser diode controller can then be used to increase DC voltage to the proper level. In addition to providing a TEC for temperature stabilization, the HLD001 mount is also designed to assimilate into a flexure platform. Since the output of a laser diode is highly divergent, collimating optics are often necessary. This device is based on quantum well epitaxial layer growth and a highly reliable ridge waveguide structure. This pin is connected to the 9 o'clock and 3 o'clock pins on the laser socket and corresponds to the settings of the LD and PD polarity switches. We will look into adding sockets to improve the ease of mounting. Prior to installing a laser diode in the mount, the pin configuration style must be determined and the mount properly configured to power the diode. Designed to work with our LDC controllers the TEC Lockout can easily be bypassed by setting an on-board jumper. LM14S2 - Universal 14-Pin Butterfly Laser Diode Mount : Zoom. Lasers / Coherent Sources Thorlabs provides an extensive selection of lasers and other specialized coherent sources, such as our correlated photon-pair source. When setting the modulation voltage, it is recommended to start at a factor of 10 lower than the value determined from Eq. Ø5.6 mm and Ø9 mm TO Can KitsEach LDH56-P2(/M) or LDH9-P2(/M) Collimation Mount Kit includes cage plates for mounting either a Ø5.6 mm or Ø9 mm laser diode, an M9-threaded cage plate for holding a mounted aspheric lens, and four 1.5 long cage rods. If it's still offset with respect to the cage, perhaps the simplest solution would be to use a KCB1 mirror mount to steer the beam within the cage. To determine what magnification of the minor axis is needed to produce a round beam, solve Eq. Full details of the assembly and operation of the LDM9T Mount can be found in the operating manual. My brother bought these, but he has now moved to college. This equation yields the focal length to achieve our desired major (perpendicular) axis diameter. The LDM9T is not compatible with any style F connections, even though the configuration is very similar to the D style configuration. Always mount the laser in a suitable heat sink to remove excess heat from the laser package. As with style A, B, and C laser diodes, style D laser diodes feature a laser diode and monitoring photodiode; however, in contrast, style D contains two ground pins instead of only one. The PS881-B Mounted Anamorphic Prism Pair features SM05 threading on the output end or may be mounted inside an SM1 Lens tube. Thorlabs specializes in the building blocks for laser and fiber optic systems. The LM14S2 supports maximum laser and TEC currents of 5 A each. To allow high frequency modulation of the laser diode, the mount's built-in bypass needs to be used to circumvent the low pass filter. As determined in the example above, a 3.5X mounted anamorphic prism pair (i.e., PS881-B) was needed to produce a round beam profile. Thorlabs offers a large selection of aspheric lenses. Please note: The LDM9T mount is NOT compatible with style F 4-pin configurations. Options range from individual laser diodes and DPSS lasers to complete laser solutions such as fiber-coupled lasers, HeNe lasers, femtosecond lasers, and nanosecond pulsed lasers. In the above example, the C171TMD-B mounted lens features M8 x 0.5 threading, thus requiring the S05TM08-threaded adapter. Again, adjustment of the aspheric lens can be made at the LMRA5 and SM1A6T adapters. These collimation packages allow researchers to mount and collimate a laser diode. The TTC001 T-Cube™ Temperature Controller is often used in applications that utilize the HLD001 mount. The LM14S2 supports maximum laser and TEC currents of 5 A each. Additional safety and protection features include on board reverse bias protection diodes, remote safety interlock connection, and the TEC Lockout circuit that prevents enabling of the laser diode unless the temperature controller is also enabled.
