The LDP-3830 Pulsed Precision Current Source is specifically designed for controlling laser diodes and quantum cascade lasers. The LDP-3830 provides adjustable peak pulse current up to 5A with a compliance voltage up to 20V, adjustable pulse widths from 25 ns to 1 µs, and adjustable duty cycle from 0 to 5%.

Careful attention to the design provides for highly repeatable pulse to pulse amplitude and pulse width. Laser protection features incorporated in the LDP-3830 include redundant current limits, transient protection, floating outputs, and safety interlocks.

For seamless integration into your automated test application, the LDP-3830 comes standard with GPIB/IEEE 488.2 and USB 2.0 computer interfaces. Additional instrument flexibility is provided by trigger in and trigger out functions to control pulses and initiate corresponding measurements without a command program.
