Product Overview:

Precision 250 mA Current Source with 16 Watt TEC Controller / Compact Module

These 250 mА low noise laser diode controllers are designed to precisely provide drive current and control the temperature of temperature controlled laser diodes. These controllers are an excellent choice for product integration or for an affordable solution to laboratory test set-ups. These modules are also available with an integrated butterfly laser diode package mount.

Small Footprint Laser Diode Controller

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 58mm package.

Multiple Integrated Laser Diode Protection Features

These controllers are designed to provide a series of protection features to ensure the safety of your laser diode. The module ships with a jumper which shunt the LD bias current path of the driver to protect the laser diode from any ESD / static discharges when a user is installing the diode into the mounting socket. This shunt also protects the laser when the user is connecting the DC power, the control connector or any other external equipment. An integrated reverse diode protects the laser diode from any possibility of damage from reverse current and reverse voltage. The user can set a current limit and temperature limit through the analog control connector port on through the on-board trim potentiometers. These controllers also offer a ~ 900 millisecond soft-start ramp to the current set point to avoid the potential for thermal shock to the laser.
