This paper discusses the operating regimes of a neodymium-doped potassium g
adolinium tungstate laser in solid sapphire and quartz reflectors, as well
as in a hollow reflector using an immersion compound. With a repetition rat
e of 100 Hz, it can deliver an output energy of 0.5-5 mJ fur I - 1.5 min. (
