Precision Pulse Control for Laser Diodes and Quantum Cascade Lasers
The LDP-3830 was designed to provide safe and repeatable pulse current for laser diodes and quantum cascade lasers. The LDP-3830 is capable of delivering up to 5A peak current over a pulse width range of 25 ns to 1 µs with a maximum duty cycle of 5%. To achieve pulse widths of 25 ns with rise times less than 10 ns, the pulse circuitry is contained in the LPB-386 Pulse Board with all control functions being sent from the LDP-3830. For accurate monitoring of laser drive parameters, the LPB-386 Pulse Board has the ability to monitor the current via a switch located on the LPB-386. For quantum cascade laser applications, the LDP-3830 can deliver up to 20V of compliance with highly repeatable pulse to pulse amplitude and pulse width.
