This paper gives some results and curves from calculating the equations of a TEA CO{sub 2} laser. 3-D Chang`s electrode was precisely calculated and manufactured to gain well-distributed electric field in discharge space, which is necessary for TEA CO{sub 2} 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 CO{sub 2} laser. So, an efficient low temperature catalyst is used in this laser. The specifications of this laser are as follows: mode is TEM{sub 00}, divergence (whole angle) in far field is less than 4mrad, pulse energy of TEM{sub 00} mode is 87.8mJ, FWHF is 36.5ns, peak power of TEM{sub 00} mode is more than 0.9 MW, operating frequency is 130Hz (the maximum frequency is up to 255Hz and it can operate continuously at 50Hz), its operating life is more than 1 {times} 10{sup 7} shots.
