Abstract

The studies on a short pulsed TEA (Transversely Excited Atmospheric pressure) CO₂ laser pumped by a magnetic pulse exciter are reported. The exciter includes a magnetic pulse compression circuit, which compresses the pulse duration below 100 ns. According to our experiments, the maximum output energy of a single pulse can be as high as 2.84 J and the Full Width at Half Maximum (FWHM) of the laser pulse is 70ns approximately. The pulse shapes and characteristic times are measured. The results indicate that the single pulse energy keeps a linear relation with the gas pressure and charge voltage. And there is an optimized composition that the maximum output pulse energy or shortest pulse width can be obtained. Based on this free oscillation laser, a tunable TEA CO₂ laser is developed. Over 62 laser lines from 9.16 to 10.79μm have been obtained and the output pulse energy of 10P(20) line is 0.5 J.
