Abstract

This paper describes the results achieved in the development of a chemical oxygen iodine laser (COIL) for industrial applications. The COIL was designed to obtain kW class output power with jet type singlet oxygen generator (SOG). The output power with subsonic flow was 230 W at 15 mmole/sec chlorine flow rate. The real-time holographic interferometer with a digital high-speed camera was applied to the visualization of mixed gas flow in COIL. The visualization of gas flow shows the profile of the variation of refractive index and can be applied to the measurement of the variations in the pressure and the temperature of the gas.
