Paper Abstract

A compact transversely excited atmospheric nitrogen laser is described. A modified arrangment of an energy storage element in Blumlein excitation circuit significantly decreased the dimensions of the laser. By the use of a small low-inductive sparkgap, an efficiency of energy transfer has achieved value of more than 0.35%. With such a high efficiency the laser may operate at comparatively low charging voltage range of 3kV to 6.5kV, producing pulsed coherent radiation with peak output power of up to 300kW. A low charging voltage has been chosen to avoid electrical breakdown in the air in tropical climates.
