Characteristics of a Cataphoresis He-Ca+ Recombination Laser

A cataphoretic input of calcium vapour into the active volume of pulsed He–Ca+ laser is designed and made. The recombination laser at 373.3nm and the R-M transition laser at 854.6nm are achieved experimentally with modified Blumlein circuit by high-frequency longitudinal pulsed discharge. The dependences of work parameters such as the pulse frequency, the power supply voltage and the helium pressure on laser output characteristics at 373.3nm line are measured and discussed. The maximum laser output power of 136mW and the specific power of 5.9 mW/cm3 are obtained, respectively.
