A cataphoresis discharge tube of 7mm inner diameter and 38cm active length was made for the He-Sr+ laser. The recombination laser at 430.5nm and the R-M transition laser at 1.03μm were obtained with the modified Blumlein circuit by high-frequency longitudinal pulsed discharge. The laser components are concentrated on the 430.5nm wavelength. Dependence of working parameters, such as the pulse frequency, the supply voltage and the helium pressure on laser output characteristics were measured and discussed. The maximum laser output power of 819mW and specific power of 56mW/cm3 were obtained.
