OELDC Laser Diode Controller combines ultra-stable temperature controller and accurate constant current driver. It is ideal to drive laser diode module (transmission laser diode, pump laser diode, etc.), semiconductor optical amplifier (SOA), super luminescent diode (SLD) and light emitting diode (LED). Two PI loops monitor and control both laser diode current and temperature. The controlled laser diode current range is  20mA~500mA (OELDC-500, OEBLS-300),  50mA~800mA (OELDC-800, OEBLS-300) with option to 1.0A driving current, or 80mA~3000mA (OELDC-3000). The thermoelectric cooler (TEC) control current is from 1.2A,  2.0A up to 2.2A. With on-board Butterfly solder pads or DIP-14 connector, mounting Butterfly packaged module or DIL-14 packaged module is easy and reliable. Adjustable current limitation and slow-start can protect the laser diode modules.
