Abstract

We present the results of stability studies of nanosecond light sources based on single quantum well (SQW) InGaN/GaN ultra bright blue LEDs. It is shown that the light yield of such light sources and their timing characteristics don't deteriorate even after 1010 total pulses. The longterm stability of the sources light yield is better than 1%.
