Thank you for contacting Thorlabs. Thorlabs offers laser diode mounts for Ø3.8 mm, Ø5.6 mm, or Ø9 mm TO can packages. Please note that there is a difference between style D 4-pin and style F 4-pin (described below) configurations. Threshold Current referenced on the attached data sheet is 30 mA with slope efficiency of 0.25. This mount does not support this feature. If the LD and PD switches are set to AG then this pin grounds the Anodes of the laser and photo diodes. Note: only cylindrical lens pairs can correct for any astigmatism present in the diode output. Use the descriptions and schematics below, along with the appropriate style pin code (A - F), to properly power the laser diode. See the Pin Configurations tab for more information on Style E compatibility and necessary modifications to the mount. It can then be mounted in the SM1A6T SM1-to-SM05 adapter. Grounding the photodiode pin will allow the mount to drive a laser diode only (no photodiode) configuration with the LD pins at the 3 o'clock and 9 o'clock positions. Thorlabs - HLD001 Laser Diode Mount With Thermoelectric Cooling Products Home / Multi-Axis Stages / Accessories for Flexure Stages / Laser Diode Mount with TEC / HLD001 HLD001 - Laser Diode Mount With Thermoelectric Cooling 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. 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. There are four pin configurations (A, B, C, and D), which are completely compatible with the LDM9T mount. For driving higher power laser diodes, the LDC220C and LDC240C offer drive currents of 2 A and 4 A, respectively. Aided by an integrated low speed fan, the temperature range is approximately 20 to 30 °C. Hi, I am selling this brand new LM14S2 - Universal 14-Pin Butterfly Laser Diode Mount from ThorLabs. When setting the modulation voltage, it is recommended to start at a factor of 10 lower than the value determined from Eq. Thorlabs Laser Diodes, Unbiased LASER DIODE SELECTION GUIDE, Compare all Manufacturers and Product Data Sheets on One Site, 370nm to 2350nm Thorlabs' LDC2xxC series of controllers are suitable for use with a large majority of popular laser diodes. A TEC power supply is included with the LDM9T. To collect as much light as possible during the collimation process, consider the larger of these two divergence angles in any calculations (i.e., in this case use 30o). LDM56F Mount Compatibility. The advantage to using the LDC202C controllers is that they will have a higher compliance voltage and higher modulation frequency bandwidth. With this configuration, it is not possible to apply the correct voltage bias across both diodes simultaneously using the LDM9T laser diode mount. The modulation voltage can then be slowly increased until VRF or the desired modulation is achieved. Do you offer any cable which is compatible with the HLD connector? Take care to ensure that the lens does not contact the laser diode. If this is not an option, the HLD001 is certain worth looking into, but there are a few things you should note. The SM1 threading of the adapter can then be used to attach the lens/mount/adapter to the laser diode mount's front plate. Always mount the laser in a suitable heat sink to remove excess heat from the laser package. Laser Diode Mount with Integrated TEC and Controller, Laser Diode Mount with Integrated Temperature Controller, Metric, Laser Diode Mount with Integrated Temperature Controller, dual laser diode current/temperature controllers and kits, Strain Relief Cable for Diodes with ESD Protection, SM1 (1.035"-40) Threaded Aperture and 30 mm Cage System Holes, 3.09" x 2.89" x 1.79" (78.5 mm x 73.3 mm x 45.5 mm). Maximum amount of heat that can be absorbed at the cold face of the TEC. In addition, the mount is compatible with all of our currently available 4-pin laser diodes with a style D configuration (see Fig. Pigtailed Laser Diode, SMF from Thorlabs. Software for Laser Diode Controllers. In these configurations, the laser diode houses a monitor photodiode tied to either the cathode or anode ground of the laser diode. These laser diodes only contain a laser diode and ground pin, as shown to the right in figure 1. Operating current at 10 mW for this 405nm laser â¦ Otherwise it is floating. Easy to use polarity switches allow the laser mount to be configured for most laser pin assignments (see Pin Configurations tab). The LDM9T Mount is also compatible with style E and H laser diodes, which do not have a corresponding photodiode. 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). I have no idea what they are for. The laser diode controller can then be used to increase DC voltage to the proper level. Mounted and unmounted aspheric lenses with focal lengths greater than 8 mm can be cage mounted using our 30 mm cage system. The LM14S2 also includes a laser diode TEC lockout feature a that disables the laser when the TEC controller is not active. The top surface The LM14S2 supports maximum laser and TEC currents of 5 A each. The PS881-B Mounted Anamorphic Prism Pair features SM05 threading on the output end or may be mounted inside an SM1 Lens tube. The LM14S2 also includes a laser diode TEC lockout feature a that disables the laser when the TEC controller is not active. Temperature stabilization of laser diodes is necessary for applications which require substantial control over a diodes power and wavelength. Since the LD and ground pins are directly across from each other (i.e,. 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. The CP33(/M) cage plate may be used to hold the S1TMxx adapter with mounted aspheric lens or the SM1A6T adapter with unmounted aspheric lens epoxied to an LMRAxx adapter. 4 peltier negative (top plate will cool down) Higher current (5 and 20 A) and rack mount controllers are also available. Part Number: LM14S2 -Ask a technical question Ask a technical question. To calculate the focal length needed to achieve a Ø3 mm collimated beam diameter, we can use: where is the focal length that produces the desired perpendicular beam diameter, . 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). Also, reverse voltages as little as 3 V can damage a laser diode. For mounted aspheric lenses, our SM05Txx or S1TMxx adapters can be used. 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. 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. Style G configurations feature only a laser diode in the package; no photodiode is present. Full details of the assembly and operation of the LDM56F Mount can be found in the LDM56F operating manual. This 785nm device features high optical output power and slope efficiency. Accessories such as laser diode sockets and collimation packages are also available. Otherwise it is floating. 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. The LDM9T is directly compatible with Thorlabs' LDC Series controllers. The LM14S2 supports maximum laser and TEC currents of 5 A each. In order to use the mount with any other laser diode style will require undoing the modification performed above. Contact Tech Support for more information. Could you tell me if this mount is suitable for hooking upto an ITC4001 controller and if so what cables should be used? And regarding the thermistor, is there a polarity? 1 peltier positive (top plate will cool down) 458 www.thorlabs.com Laser Diode Technologies Benchtop Drivers Platform Drivers OEM Drivers Laser Diode Mounts Laser Diodes Pigtailed Lasers Laser Modules Accessories LASER DIODE MOUNTS The LM14S2 Butterfly Laser Diode Mount is designed to operate with all lasers and two-port electro-optic devices in a 14-pin "butterfly" package. 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. There is no suppression of noise or other spurious signals to the laser diode. Thorlabs specializes in the building blocks for laser and fiber optic systems. Laser diode current controllers should be chosen based on the actual laser diode used and the particular application. SM1 (1.035"-40) Thread and 30 mm Cage System Compatible The LDM9T is a laser diode mount including an integrated thermo-electric cooler (TEC) and temperature controller to precisely regulate the operating temperature of a laser diode. Stable and clean RF sources should be used to avoid overdriving the laser diode. There are two switches located on the top of the mount that control the polarity of the laser diode and monitor photodiode, if present. 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. To calculate the beam size of a collimated laser diode, we first need to know its divergences. All of the controllers include a compatible. 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. 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. Mounting collimating and other optics is easy using standard Thorlabs optomech parts. 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). You should also be sure to make sure that this TEC can handle the heat generated by your diode. NEW LM14S2 - Universal 14-Pin Butterfly Laser Diode Mount from ThorLabs. The TEC element contained in this mount can sink up to 3 A to keep the laser diode at a constant temperature. The major (perpendicular) beam divergence is shown in Figure 1.
