Abstract
This paper presents the analysis and experimental research of an original scheme of the solid-state laser resonator, capable of emitting subnanosecond radiation pulses with controllable duration. For this purpose, it is proposed to use the controllable Michelson interferometer, containing an electro optical phase modulator as a composed output resonator mirror. In this case, the interferometer provides the active resonator mode locking as well as the fast resonator Q-switching mode for effective generation of the output radiation pulses with variable duration.
Key words
Ultrashort pulse emitter, controlled Michelson interferometer, electro-optical modulator.
