• USB and GPIB computer interfaces
• Compatible with ILX LDM-4872 Quantum Cascade Laser Mount

The LDP-3832 Pulsed Quantum Cascade Laser Current Source is specifically designed for controlling quantum cascade lasers in sensitive spectroscope applications. The LDP-3832 provides peak pulse current up to 5A with a compliance voltage up to 20V and adjustable pulse widths from 20 ns to 1µs.

Careful attention to the design provides for highly repeatable pulse to pulse amplitude and pulse width 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.
