Abstract:

The results of a previous study of the concept of a stirred reactor laser with lasing restricted to the zeroth fundamental band are compared with the predicted power output of a multilevel laser for the hydrogen-fluorine- helium h2-F2-He system. Lasing is assumed to occur on all fundamental bands for which the calculated maximum gain equals the cavity threshold value. Power output is significantly increased over the zeroth band calculations, and the effect of cavity pressure is shown to be less pronounced because of the cascade enhancement from higher bands. Vibrational de-excitation caused by collisional processes appears to limit this kind of chemical system to low cavity pressures. The effect of cavity losses was evaluated with three assumed values for the cavity loss coefficient. These values were estimated as a small fraction 0.1 of the average small signal gain coefficient at different cavity residence times.
