The LDP-3830 Precision Pulsed Current Source is specifically designed for controlling laser diodes and quantum cascade lasers and is ideal for single-emitter VCSELs or VCSEL arrays. It provides an adjustable peak pulse current of up to 5A with a compliance voltage of up to 20V, adjustable pulse widths from 25 ns to 1 µs, and an adjustable duty cycle from 0.01% to 5.00%.
Careful attention to the design provides for highly repeatable pulse-to-pulse amplitude and pulse width. Laser protection features are incorporated in the LDP-3830 including 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 488.1 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. For virtual instrument programming, LabVIEW® instrument drivers are available free of charge. LabVIEW® instrument drivers can be downloaded from the Literature and Downloads tab on this page. The LDP-3830 has a 200-240 VAC power requirement.
