He–SrCl2 vapor laser excited by Blumlein discharge circuit

An investigation of a He–SrCl2 vapor laser excited by Blumlein discharge circuit is performed. Dependences of laser output power on the working parameters are obtained by experiment. The optimal operating parameters for lasing on several strontium atom and ion lines are found. The multi-line average output power of 1.32 W and the power specific of 12.46 mW/cm3 are achieved, of which more than 78.1% is concentrated at the 6.45 μm laser line.
