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 TEC element contained in this mount can sink up to 3 A to keep the laser diode at a constant temperature. Temperature stabilization of laser diodes is necessary for applications which require substantial control over a diodes power and wavelength. Thorlabs offers a wide variety of Temperature and Current Controllers suitable for laser diode temperature and current control. The TTC001 T-Cube™ Temperature Controller is often used in applications that utilize the HLD001 mount.

In addition to providing a TEC for temperature stabilization, the HLD001 mount is also designed to assimilate into a flexure platform. The mount features an alignment key that mates with a keyway of a flexure platform; yielding a simple and accurate method to integrate this mount into a flexure assembly. Integration into these multi-axis flexure mounts provides excellent control over a diode's position and alignment with optical systems.

Do you offer any cable which is compatible with the HLD connector? If not, for connection to a CAB420: the CAB diagram shows three pins per polarity for the TEC (3 + and 3 -). Can I just connect one of each to the HLD? And regarding the thermistor, is there a polarity? The CAB diagram shows one, but the HLD doesn't.

thank you for your inquiry. we do offer a connecter with the HLD but you would have to make you cable. here is the pin out : 1 peltier positive (top plate will cool down) 2 thermistor 3 thermistor 4 peltier negative (top plate will cool down) hope this helps. If you have any further questions with your application please get in touch with your local tech support team, who'd be happy to help.

Response from Chris at Thorlabs to Andrew: Thank you for using our webfeedback. If beam pointing is an issue, I would first check to make sure the diode itself is mounted securely in the TCLDM9 with the appropriate flange. 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. If this is not an option, the HLD001 is certain worth looking into, but there are a few things you should note. There is no cable directly compatible with both of these devices so in order to used them together you would need to solder one using the extra connectors provided with the ITC and the socket provided with the HLD001. You should also be sure to make sure that this TEC can handle the heat generated by your diode. The capacity of the mount is 6.3 Watts, as opposed to the TCLDM9 which has a 20 W capacity.

Hi, Could you tell me if this mount is suitable for hooking upto an ITC4001 controller and if so what cables should be used? I'm using a UV, 5.6mm, style B laser diode. FYI I Currently use several TCLMD9 and LDM21 mounts but have a few issues with these, the very large cables and connectors take up a lot of room and put a lot of torque on the mounts, it's hard to keep them stable amd firmly positioned with just a 1/2" post. The beam coming from a mounted 5.6mm diode in one of these mounts is usually to off axis to use with a cage system as well, do you think a HDL001 mounted on a kinematic platform will be a worthwhile upgrade?
