BOZEMAN, Mont., Aug. 17, 2010 — For absorption spectroscopy using quantum cascade lasers, ILX Lightwave Corp. has unveiled the LDP-3832 pulsed quantum cascade laser driver that provides peak current up to 5 A with a compliance voltage of up to 20 V and adjustable pulse widths from 10 ns to 1µs, with adjustable duty cycles up to 5%. It includes a precision 500-mA DC current source with a modulation bandwidth greater than 10 kHz for biasing the laser. Careful attention to the design ensures highly repeatable pulse-to-pulse amplitude and pulse width control with fast rise/fall times of <5 ns and overshoot of less than 5%. Laser protection features include redundant hardware and firmware current limits, transient protection, floating outputs and safety interlocks. Integrated current and voltage monitors allow precise pulse waveform monitoring. For easy system integration, input and output trigger functions can be used to control current pulses and to initiate external measurements without the need for programming. IEEE/GPIB 488.2 and USB computer interfaces allow easy remote programming and control in automated test systems where repeatable and accurate test sequencing, measurements and data handling are required. LabView drivers are available from the company’s website.
