Paper Abstract

The recently demonstrated high-power (50W from a 20μm stripe) picosecond (30ps) lasing from a laser diode has led us to address the internal Q-switching phenomenon, discovered four decades ago and not yet fully understood. We found that the realization of a nanosecond or picosecond mode in a diode depends on the doping profile across the structure.
