The voltage oscillation in the spark gap, laser cavity and in the Blumlein circuit has been described briefly. The laser pulses at central wavelength of 337.14 nm with pulse duration of 1.5 ns at atmospheric pressure are obtained from the constructed prototype laser. The optimization of the spark gap, variation of the inductance and resistance of the spark gap, geometry of the discharge channel of laser, observance of beam spot and electric field to pressure in the discharge channel of laser are measured and calculated. The investigation about the discharge channel voltage, current and their dependence upon the time dependent inductance, time dependent resistance of spark gap for different resistive phase period has been investigated for the optimization of the constructed TEA nitrogen laser system.Gas lasersTEA Nitrogen LaserInductance of Spark gapResistance of Spark GapArticle
