Description/Abstract

An electro-optic Q-switch has been opened in two steps to allow slow pulse build-up giving, in conjunction with a resonant reflector, a high degree of mode selection in a way analogous to the use of saturable absorbers. Using this technique, a flash pumped Nd:CaWO4 laser has produced reliable operation in a single longitudinal and transverse mode with an output power of 250 kW.
