Abstract
An optical system is proposed in which a switch based on frustrated total i nternal reflection (FTIR) is used to vary actively the Q-factor of longitud inally pumped erbium glass microlasers. Continuous pumping (with a power of 320 mW) generated giant pulses, of 500 - 600 W peak power and of 10 - 12 n s duration, at a repetition rate of 1 kHz. An FTIR switch in a laser transv ersely pulse-pumped by a linear laser-diode array delivering 100 W produced pulses of up to 7.5 mJ energy and of 30 ns duration.
