Laser Diode Drivers

The PPS series analog laser diode drivers/controllers manufactured by Portable Power Systems Inc. can operate in pulsed or continuous-wave mode. Depending upon the unit, voltages range from 0 to 250 V, and currents range from 0 to 300 A. Rise times of 15 µs and pulse widths of 25 µs are possible. Most units house a universal input power supply that accepts voltages of 85 to 264 VAC. Higher-power units can work with an external power supply to reach higher power levels. The current can be controlled by a potentiometer on the front panel or by accepting a 0 to 10-V analog signal via the rear panel. Medical applications include photodynamic therapy and vein cauterization.
