Experimental study of an SF6Brillouin amplifier pumped by KrF laser radiation

摘要

Experimental measurements are presented of the gain for a backward Brillouin amplifier using SF6gas, in the pressure range of 3ndash;10 atm, pumped by KrF laser radiation. A small signal gain of 6times;10minus;4cm MWminus;1, pump depletion of 20percnt;, and an intensity gain of 2.5 have been demonstrated.
