Paper Abstract

The studies on a 1 00-Joule-class UV-preionized TEA (transversely excited atmospheric) CO2 laser are reported. A maximum pulse energy 1 15 J was obtained by using an energy-optimized gas mixture of C02/N2/H2 =3/15/2 and a Marx pulse generator discharge circuit. The temporal waveform of the laser pulse with the optimized gas mixture consists of a sharp spike of 250 ns and a tail of 4 µs in full width at half maximum (FWHM). Simple air breathing laser propulsion was demonstrated, a high impulse coupling coefficient 390 N/MW was obtained at the pulse energy 60 J, which shows the attractive point ofthe UV-preionized TEA CO2 laser.
