The ILX Lightwave LDX-36040-70 High Power Laser Diode Driver is a 40A and 70V current source that offers CW, QCW, and Hard Pulse Output with multiple levels of laser diode protection. The LDX-36040-70 can be operated at full scale current and voltage in CW or QCW mode saving time and reducing cost of test by eliminating multiple instruments and test set-ups. Conduct CW L-I-V testing and pulse testing of high power laser diodes all at the same test station, without moving the laser or changing the output cable. With the 36000’s there is no need for another QCW instrument, simply change operating modes from the front panel or through the GPIB interface, set up the test parameters and start testing quickly in either mode. In QCW mode, the pulse output can be generated either internally with programmable pulse width, duty cycle and frequency parameters or through an external pulse trigger, output up to 80A at 70V. In addition the LDX-36040-70 features 4-wire voltage measurement, photodiode measurement, and a trigger in and out. For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the GPIB/IEEE-488 interface. Specifications. Output Current Range: 0 to 40 A.
