Integrated 1.5 Amp Laser Diode Driver with TEC Controller

Product Overview:

Advanced Performance Laser Diode Control and Mount Module

These hybrid laser diode control electronics and mounting modules offer an all-inclusive, high performance solution for controlling laser diodes. These controllers are an excellent choice for integration into a laser system product or as an affordable solution for laboratory test set-ups. Key features of these modules include a low noise laser diode current source to safely electrically bias your laser diode and an integrated TEC / temperature controller. They also include multiple control interface options to enable you to control all of the parameters of your laser diode. Interfaces include on-board potentiometers, an RS232 interface, a USB interface and an analog control signals connector.

• On-Board Component Level Protection Against Input Power Surges and Reverse Voltage Transients: An integrated on-board zener diode in parallel with the bias current path protects the laser diode from damage which can occur from reverse voltage transients. These transients can occur when a standard DC power supply source is momentarily interrupted due to a black-out or brown-out power outage.

 

• User Adjustable Current and Temperature Limits: The user can set current limit and temperature limits through on-board potentiometers. Limits can also be set using your PC through the included control software. Finally, limits can be set using the analog control signals input. Setting limits are necessities to ensure a long life-time for your laser.

 

• ESD Protection; Bias Current and DC Power Shunting Clip: These module ship with a jumper clip that shunts the laser diode bias current path of the driver to protect the laser from ESD or static discharge when the user is installing the laser into the mounting socket. This shunt also protects the laser when the user is connecting the DC power or any other external equipment.

 

• Soft-Start Current Ramp: There is an internal 500 millisecond soft-start ramp to the current set-point. This reduces the potential for thermal shock to the laser at power ON and is used to ensure good electrical contact prior to fully applying the current bias the laser diode.

 

• Additional External Over-Temperature Monitor Input: Primarily designed for integration of the module into a laser system, an additional thermistor input is provided to allow the user to monitor the temperature from an external measurement point. This can then be used to shut the laser diode off if a temperature maximum for the system is exceeded.

 

Small Footprint Complete Control Solution

These modules are the smallest footprint controller which is commercially available. Careful selection of components and and exacting design criteria allows the modules to provide complete control of your pump laser in a 61mm x 101mm package. They have a 10mm thick aluminum base plate which provides excellent heat dissipation and keeps the laser diode safely operating within your desired operating temperature range. The module base plate comes with 4 mounting through-holes, 3.2mm each, to bolt the module directly to an instrument chassis or any thermally conductive surface.
