A, B, and C configuration laser diodes, two-pin style E, G, and H configurations, and all four-pin style D laser diodes. The TCLDM9 is also compatible with style G laser diodes; however, modifications of the TCLDM9 Mount are required as discussed in section 4.1. - Page 6 Temperature Controlled, Laser Diode Mount PD Switch TEC Interlock Bypass Jumper Laser On Indicator LD Switch Shield/Ground LD Controller Jumper Connetor RF Input (SMA) TEC Controller Connetor Remote Interlock Figure 1 Location of Features 1981-D03, Rev N June 26, 2015...

The other laser and photodiode pin will be isolated from the case. The TCLDM9 was designed to operate the laser case at ground potential therefore this common pin will be inserted into either the 12 o’clock or the 6 o’clock position of the laser connector. - Page 8 In order to drive a style G laser diode, the PD pin in the mount must be grounded. To ground the PD pin, remove the front cover to the TCLDM9 mount. Locate jumper J4 on the right-hand side of the mount. A photo of the TCLDM9 internal circuitry is shown in Figure 4, and jumper J4 is marked with a red arrow.

TCLDM9 are consistent with each other. For example, if the laser polarity on the driver is set to AG (anode grounded), then the LD polarity switch on the TCLDM9 should also be set to AG, and so forth. •... - Page 10 Signal Description This pin is the input to the LD Status Indicator and Interlock Interlock and Circuits. When using Thorlabs LDCs no external circuitry is Status Pin required. To use these features with third-party controllers (LDC Specific) please refer to the Status and Interlock section of this manual.

4.3.1. Using the Thorlabs TED Series TEC Controllers The TCLDM9 is best used with Thorlabs TED200 or related TEC Controllers. The TED series are shipped with a mating DB9 cable that plugs directly into the controller and laser mount. Using the cable supplied with the TED, the controller cannot be connected incorrectly. -

Temperature Controlled, Laser Diode Mount Chapter 4: Setup 4.4.2. The TEC Lockout and Ground Jumpers Two jumpers, JMP1 and JMP2, are located under the cover on the main PCB assembly. JMP1 allows you to enable or bypass the TEC Lockout feature. This feature, when enabled, will prevent the laser diode from being turned on unless the TEC controller is enabled. -

4.5. Making the Safety Interlock Connections The TCLDM9 is equipped with a Remote Interlock connector located on the side panel. In order to enable the laser source, a short circuit must be applied across the terminals of the remote interlock connector. In practice this connection is made available to allow the user to connect a remote actuated switch to the connector (i.e. -

5.1. RF Modulation The TCLDM9 has an RF input for modulating the laser with an external RF source up to 500 MHz. This is a 50 Ω 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... - Page 16 Temperature Controlled, Laser Diode Mount Install the TEC LOCKOUT bypass jumper into JMP1 inside the TCLDM9. (See “The TEC Lockout and GROUND Jumpers” above). Connect a resistor to LD Interface DB9 Pin 1 appropriately sized to limit the current into Pin 1 to between 5 – 10mA.
