Current Pulsers and Laser Diode Drivers (Pulsed Current)

These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

To select the ideal pulser:

Avtech can often customize pulse parameters and provide device socketing to meet particular requirements.
