Abstract

We report characteristics of laser induced gas breakdown by changing wavelengths, gas media as well as controlling energies. Pulsed YAG laser beam was focused into the gas chamber in order to study breakdown thresholds and laser transmission through produced plasmas. Laser transmission indicates a lot of information about breakdown threshold and transmission properties. Experimental data indicate that combination of shorter wavelength, shorter focal length, Ar gas of higher pressure is suggested for plasma generation.
