Product Overview:


These fully integrated laser diode controller and mounting modules for butterfly packaged devices are designed for cost effective precision control of single mode and single frequency semiconductor lasers in research labs. These controllers provide a low noise CW laser diode current source and a high efficiency TEC controller with a pre-configured mounting socket. The mounting plate for the laser has a high surface flatness and finish to provide a low thermal impedance between the package at the heat sink base. The standard pin configuration is the "Type 1" package style. "Type 2" and other package configurations are available on request.


The integrated laser diode protection circuits protect your device under test at all times. A user set current limit and user set temperature limit clamp both the bias current and the operating temperature to prevent damage to the laser. A soft-start current ramp to the user defined current set-point protects the laser from the possibility of thermal shock or current surges. Also, the integration of the mounting socket directly with the current source eliminates the need for cables and connectors from the current path. This greatly reduces the likelihood of ESD damage to the laser which can occur from plugging and unplugging cables. Set-point and limits are set using a simple one screen graphical user interface which is opened when you connect your PC to the USB interface. The GUI control software is included with the purchase price and offers users simple set-up and control.
