Pulsed laser evaluation of single event transients in optocouplers

A methodology which used pulsed laser to evaluate the Single Event Transients (SETs) in the optocouplers was proposed. The SETs responses of the optocouplers were firstly investigated with the experimental simulation by pulsed laser test facility. The pulsed laser test data was compared with the ion test data to indicate the veracity and to provide insights into the SETs mechanism. The SETs characters induced by pulsed laser were qualitatively analyzed in model theory.
