402206 Newport Power Board

The Newport / ILX Lightwave LDX-36000 Series High Power Laser Diode Current Sources are capable of delivering very high currents, up to 125A CW and 220A QCW with a compliance voltage up to 35 Volts. These current sources are designed for testing and controlling multiple high power laser diodes with specially designed features such as high set-point accuracy, low output noise, forward voltage, and photodiode measurement and an adjustable photodiode reverse bias voltage.

These current sources also offer many laser diode protection features which protect the laser diode during testing from electrical transients and providing safeguards such as adjustable voltage and current limits. Low current overshoot in either CW or QCW mode and closed loop power supply control prevent surge currents in the case of a device failure with multiple diodes connected in series. A thermistor based temperature monitor provides additional protection through a programmable temperature limit which can be used to disable the laser output when a temperature limit is exceeded. Dual independent interlocks are provided for further laser and operator protection.

Remote instrument operation is possible on all LDX-36000 Series Current Sources through an IEEE488/GPIB interface. All instrument controls and functions are programmable for test sequencing, measurements and data handling in automated test systems. Synchronization with other measurement or control instruments is possible with an input and output trigger function with programmable delays. Multiple test configurations can be saved and easily recalled through Save and Recall functions from the front panel or through the GPIB interface.
