Abstract

A hybrid oxygen-iodine laser (HOIL) using discharge singlet oxygen generator (DSOG) was studied experimentally. We used a microwave discharge as a plasma source. The microwave frequency was 2450 MHz and the input power for discharging was up to 30 W. Oxygen excitation tests were carried out using the DSOG by changing conditions of input power, oxygen pressure and flow rate, gas-mixing ratio, and so on. Spectrum analyzer was used as a diagnostic device for measuring the singlet oxygen of its wavelength 1.27 micrometer. The best results of excitation efficiency was 21% on condition that oxygen output pressure was 1.4 - 1.9 torr and oxygen flow rate was 30 sccm.
