Paper Abstract

This paper gives some results and curves from digital calculating about equations of TEA CO2 laser. 3D Chang's electrode was precisely calculated and manufactured to gain well-distributed electric field in discharge space, which is necessary for TEA CO2 laser. A pre-ionization technique used in this laser was described. A gas circulating system was designed to let the laser operate at high repetition frequency (HRF). It is a key technique to extend the operating life of mini high repetition frequency sealed-off TEA CO2 laser. So, an efficient low temperature catalyst is used in this laser. Mini HRF sealed-off TEA CO2 laser can be applied for the military such as rangefinder, tracing, designating, etc. The specifications of this laser are following: mode is TEM00, divergence (whole angle) in far field is less than 4 mrad, pulse energy of TEM00 mode is 87.8 mJ, FWHF is 36.5 ns, peak power of TEM00 mode is more than 0.9 MW, operating frequency is 130 Hz (the maximum frequency is up to 255 Hz and it can operate continuously at 50 Hz), it's operating life is more than 1 X 107 shots.
