Some features of stimulated emission from a dye laser pumped by a finite train of ultrashort pulses. II. Reduction of the pulse duration due to stimulated deexcitation of the active medium

Deexcitation of dye molecules by the stimulated emission was used to reduce the duration of the ultrashort pulses from a synchronously pumped dye laser. This accelerated the formation of the output pulses and stabilized their profile. Mathematical modeling showed that the pulse duration could be more than halved by selecting a suitable delay and deexciting pulse energy.
