Page 3: Description
The TCLDM9 was designed with features that allow it to be easily incorporated into complex systems. The front of the TCLDM9 has a 1.035”-40 thread to accept a wide variety of Thorlabs SM1 1” optics mounts and accessories. Also standard with the mount are 4-40 tapped holes on 30mm centers for mounting any number of Thorlabs cage assembly products. -

Special note for 4-pin laser diodes: The TCLDM9 also supports 4-pin laser diodes. Insert the laser into the 4-pin socket and note which laser pin is in the 3 o’clock position (laser anode or cathode). Also note which photodiode pin is in the 9 o’clock position (anode or cathode). -

• The TCLDM9 is best used with Thorlabs LDC Series Laser Controllers. The LDC series drivers are shipped with a mating DB9 cable that plugs directly into the controller and laser head. Using the cable supplied with the LDC, the controller cannot be connected incorrectly. -

Mounting ThorLabs Fiber Coupled Pigtailed Lasers: Use the Pigtail Adapter clamp to hold the pigtail housing onto the TCLDM9 cold-plate. Referring to Fig. 4, first install the pigtailed laser into the TCLDM9 socket, observing the proper polarity of the laser to the socket (the pigtail’s pin-outs are provided with the pigtail data sheet). -

RF Modulation: The TCLDM9 has an RF input for modulating the laser with an external RF source up to 500 MHz. This is a 50Ω input that is AC-coupled directly to the laser through a Bias-Tee network. To calculate the desired RF power to modulate the laser determine the amount of modulating current needed from the laser manufacturer’s data sheets and use the following... -

2) Laser wavelength or power is unstable even though the TEC controller shows a stable temperature… Make sure your laser diode is fully inserted into the TCLDM9 laser socket and its body is in full contact with the copper cold plate. - Page 13 Waste treatment on your own responsibility If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.
