The electrical and optical characteristics of a high power UV LED (365 nm wavelength) were evaluated under pulsed operating conditions for pulsed power applications. Measurements were made over varying pulse width (30 ns–100 μs), current (0 A–250 A), repetition rate (single shot −1 MHz), and temperature (23° C–80° C). Diagnostics used included a calibrated photodiode operating in the linear regime...
The power output, forward voltage, conversion efficiency, and spectral characteristics of a 365 nm ultraviolet light-emitting diode (LED) were measured for applications of triggering wide-bandgap photoconductive switches for pulsed power applications. Pulsed currents through the LED ranged from 125 mA up to 2.2 A at widths from 10 $\mu \text{s}$ up to several seconds. Using time-resolved electroluminescence...
