Abstract:

A nitrogen laser oscillator-amplifier system has been constructed for use as a fast pulsed light source for schlieren, shadowgraph, Moire Schlieren, or interferometric diagnostics of pulsed plasmas. It utilizes an atmospheric pressure nitrogen laser as an oscillator and a low pressure transverse discharge as an amplifier. The output beam has a rectangular cross section with dimensions 5mm x 15mm, a pulse length of about 1 nsec, and is of sufficient optical quality that it may be used for interferometry. The beam energy is about 1 mJoule per pulse.
