説明
Turbulence of a gas flow in a high-repetition-rated TEA CO2 laser was investigated with an interferogram method. The average laser power increased in proportion to the repetition rate up to 1 kpps. The clearing ratio was smaller than 2 even in the repetitive operation as high as 1 kpps. However, once arc discharge occured, the recovery time became larger by a factor of two than one after a glow discharge. Our observation showed that allowance of the medium density disturbance for stable outputs was less than 1.8%.
