Spectral and spatial selection of XeCl laser radiation by an SBS mirror

Use of SBS mirror for formation of high quality short pulses in excimer laser

“…Due to this distinction these two flows were focused in SBS medium on different distance from a lens. It allowed for these flows to provide easily a various intensity in SBS medium and effectively enough to cut of ASE component in the reflected radiation [12]. Considering that threshold increment of amplification G=25, it is possible to estimate the threshold pump power of SBS medium:…”

“…In our work of [12] the opportunity of increase of coherence radiation in the resonator of a long-pulse XeCl laser (a laser pulse is 120 ns) containing SBS mirror has been shown. Output radiation this laser represented a superposition of two beams extending under a corner to each other.…”

Use of excimer media for formation of short high-power laser radiation pulses

“…The experiments were carried out on electric-discharge laser with an active volume of 60 x 3 x 1.5 cm 3 [4,5]. Laser was excited by a two-circuit system which included the storage (100 nF) and peaking (12 nF) capacitors.…”
