Abstract: The use of optical gating by frequency downconversion to study UV optoelectronic devices provides information on carrier recombination dynamics with sub-picosecond resolution. Measurement of active LEDs undergoing current injection and measurement of stimulated emission from UV laser cavities is demonstrated.
