Abstract

A recirculating liquid nitrogen cooling system for optically pumped solid state lasers is described. It has been used to obtain cw emission from YAG:Nd3+ and ABC‐YAG at 1.06 and 2.09 μ, respectively. The system is versatile and can easily accommodate intercavity components such as an acoustic Q‐switch or a Brewster window. With 3 kW electrical input to a pair of tungsten iodine pump lamps coupled to either YAG:Nd3+ or ABC‐YAG by a double elliptical cavity, the measured liquid nitrogen consumption was ∼3.3 cm3/sec at a flow rate of 37 cm3/sec.
