250mA Low Noise Current Source for DFB / DBR Laser Diodes:
The CS151 laser diode controller module is a low noise 250 mA precision laser diode current source, a 12 watt TEC controller and a butterfly mounting socket integrated into a compact module. Multiple laser diode protection features ensure that your laser diode module is protected at all times. This module is an ideal solution for biasing low power single mode butterfly packaged laser diodes. It is used in R&D lab applications or as an OEM module for product integration. The user sets the current level and the desired temperature set-point by using the on-board potentiometers or through a connector that offers voltage control pins. Status LED's quickly show if the laser diode current and temperature controller are in an ON or OFF state. These modules are used primarily for precision control of DFB laser diodes and low current devices that require a low noise current source for sensing applications.
12 Watt High Stability TEC Controller:
These controller modules offer a PI control loop to keep you laser diode operating at a stable temperature. The temperature control feedback loop is an on-board proportional / integral control loop the controls the temperature based on feedback from the 10 kOhm thermistor in the laser. The user can adjust the on-board potentiometers to obtain the optimal PI. Also, the TEC controller can operate from and external control signal that can be connected to pin 3 of the connector J4. This input can be used if the user has a digital PID algorithm external to the controller. The user can select between internal and external control modes.
25W Heat Dissipation Capacity:
These controllers are designed to dissipate up to 25W of waste heat/power without heat sink under normal laboratory conditions. The waste heat associated with most butterfly packaged laser diodes is well under the 25W maximum. These modules do not typically require an external heatsink.
Installation Tips: We recommend that a user first attaches a high power load resistor rated for 10 watts as dummy load to be certain that all electrical connections are properly secured prior to installing the laser diode. These modules require the user to connect a -12V, GND, and +12V DC power supply for standard operation. This will power the laser diode controller (current driver and TEC controller). For standard operation, the user must connect the +12VDC supply voltage to the Vdd1 pin on the Molex 8 pin connector, and connect the -12VDC to the Vee connector. There is also an option to use a separate supply for the TEC controller for lower noise performance. Details can be found in the Operating Manual attached.
