A Regenerative Carbon Dioxide Gas Dynamic Laser.

Abstract

It has been shown that pre-heating the nitrogen gas prior to mixing it with the combusted products of hydrogen, oxygen, and carbon monoxide increases the gain of a carbon dioxide gas dynamic laser from 0.35/m to 0.77/m. The limiting power extracted reaches a maximum at a temperature of 2400 K. This produces an optimum operating temperature and the limiting power extracted can be increased by a factor of 1.42. This implies an increase of 42% in output power while maintaining a constant mass flow rate. This means that a constant level of output power can be maintained while reducing the amount of fuels needed by 30%. It is recommended that a further study be conducted to determine the effects that a heat exchanger would have on other fuels to produce a 10.6 micrometer wavelength with a possible extension into other wavelengths.
