Product Overview:

LOW NOISE DFB LASER CONTROLLER

The RLSC151 combines a constant-current mode laser diode driver and linear temperature controller in one compact, easy to use module. The ZIF-socket butterfly laser diode mount is compatible with industry standard Type-1 pin configurations from manufacturers such as NEL and Toptica-Eagleyard.

OVERVIEW

Operating the C151 is simple and straight-forward. Controller parameters are set with on-board potentiometers and DIP switches, and connections are provided for external control with analog and TTL signals. The laser diode driver operates in constant-current mode, and provides low-noise current with a low temperature coefficient of change. The laser driver has an analog bandwidth of 250 kHz; fast TTL-compatible switching is provided via an SMB connector. The current limit is user adjustable, and is hardware limited to 250 mA. The factory can set the hardware limit for custom applications; please inquire for information. The 12 Watt linear TEC controller is regulated by a built-in PI control loop, or can be controlled using monitor output and external setpoint signals. The TEC current limit is adjustable via on-board DIP switch.
