Paper Abstract

Depending on the mutual orientation of the output laser beam and direction of electric current in the discharge gap, two schemes of laser pumping by electric discharge are distinguished: longitudinal and transversal. Currently, most commercial pulsed lasers operate on the transversal scheme of excitation, with more powerful laser radiation due to higher stopping electrical power in the gas. The longitudinal scheme is used for producing a laser beam with more qualitative characteristics. In this case, due to the discharge gap length being longer than in the transversal scheme, the nanosecond electrical pulse with a higher amplitude is used. The value of the reduced electrical field strength E/P remains low for effective excitation and ionization of the gas. Typically the time of breakdown development and electric current growth is not enough for effective laser generation. We propose overcoming these shortcomings with the use of nanosecond gas discharge in the form of breakdown ionization wave.
