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.

Diode Laser Driver
D200
-
The D200 is a compact, DC-coupled fast laser driver, providing up to 4 amps of regulated constant current. A built-in edge-triggered pulse generator produces up to 1 microsecond pulse widths and 2 nanosecond transition times, capable of driving lasers with forward voltages up to 9 volts. A pulse-follower mode is also provided, accommodating externally-defined trigger widths up to 100% duty continuous-wave (CW). Power, pulse width, drive current and differential triggering functions are accessible through a ribbon cable header for embedded OEM applications. A low-inductance laser drive interface permits direct laser connection or custom interposer and flex-cable attachment.
