ILX Lightwave Corporation (Bozeman, MT) has released the LDP-3832 Pulsed Quantum Cascade Laser Driver. The LDP-3832 is designed specifically for quantum cascade lasers used in absorption spectroscopy applications and provides peak current up to 5A with a compliance voltage of up to 20V and adjustable pulse widths from 10ns to 1μs. The LDP-3832 also includes a precision 500mA DC current source with a modulation bandwidth greater than 10 kHz for biasing the laser. Laser protection features include redundant hardware and firmware current limits, transient protection, floating outputs, and safety interlocks.
