Paper Abstract

The paper reports about a new pulse-repetitive high-efficient technological CO2-laser and its applications. An original method of active medium excitation was used for laser pumping. Efficiency of the laser constructed on the basis of this method reached 12%, average radiation power 600 W, pulse power ~ 10 kW. The laser was used for YSZ powders production by successive evaporation and crystallization in the gas stream. The output rate was 15-20g/h, specific surface of the powder was up to 70m2/g. Evaporation of materials by CO2 laser was also used for ZrO2 and Al2O3 thin films deposition on stainless steel plates. The average thickness of the film was ~500nm, the deposition rate was ~10nm on the area ~1cm2 per pulse. The deposited films have high adhesion properties.
