Product Overview

The 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.
