Room temperature operating pulse rf-discharge-excited CO laser

A high power pulse CO laser operating at room temperature has been developed using the modulated pulse rf discharge excitation technique. The fast pulse response and the good reproducibility of laser pulse were obtained for pulse frequency up to 1 kHz with a stable and homogeneous discharge. A maximum peak power of 920 W with a pulse width of 1.0 ms FWHM has been attained by the optimizing N 2 and CO concentration.
