Precision Pulsed Current Source for Quantum Cascade Lasers
Source: ILX Lightwave
ILX Lightwave's LDP-3832 Pulsed Quantum Cascade Laser Current Source is specifically designed for controlling quantum cascade lasers in sensitive spectroscopy applications. It features a pulsed current output of up to 5A, 20V compliance voltage, adjustable pulse width from 10 ns to 1µs. An integrated DC current source, adjustable up to 500 mA, can be used to bias the laser and can be modulated with an external input for tuning.

Careful attention to the design of the LDP-3832 provides for highly repeatable pulse to pulse amplitude and pulse width with fast rise times while maintaining overshoot to less than 5%. An input on the LDP-3832 allows a function generator to modulate the DC bias on the pulse output for interpulse tuning of quantum cascade lasers.
The laser protection features incorporated in the LDP-3832 include current limits, transient protection, and safety interlocks. For seamless integration into your automated test application, the LDP-3832 comes standard with the GPIB / IEEE 488.2 and USB computer interfaces. Additional instrument flexibility is provided by trigger in and trigger out connectors to control pulses and initiate corresponding measurements without a command program.
