Diode Driver and Temperature Controller

Laser Diode Driver and Temperature Controller (cw and pulsed). The diode laser driver and temperature controller is a highly precise, safe and cost-efficient operating solution for continuous wave (cw) and pulsed diode lasers. The power supply unit is designed for current-stabilized control of the laser diode and is also equipped with a control unit for laser diode's controlling optical beam power in cw-mode by means of the integrated photodiode input. In pulsed mode the laser diode can be operated with the freely configurable built-in oscillator or externally using the modulation input. The temperature controllers are designed as PID controllers and configured for standard operation with NTC and Pt100 sensors. The use of silicon temperature sensors or other types is equally possible simply by altering the software configuration.Features:Precise current-controlLed continuous wave and pulse-type laser driverTwo TEC drivers with PID controllersDigital and analog modulation inputsMultiple safety circuitsStored configuration (EEProM)Very low power dissipation due to bias voltage control in cw-modeDigital control using isolated RS232 serial interfaceLaser current range: 0...2500 mALaser current resolution: 1 mALaser current accuracy: < 1 mALaser current noise: < 60 nsPulse rise time: < 10 nsPulse fall time: < 5 nsVoltage range: 1.2...5 VCurrent limit: adjustable between 0...2500 mAExternal digital modulation input: TTLTEC (Thermo-electric cooler) DriverPeltier current: max. -4...+4 APeltier voltage: max. 15 VPeltier current limit: adjustable between 0...4 APeltier current resolution: 1 mATemperature control accuracy: < 10 mK.
