Far infrared chemical lasers. Technical progress report No. 3, August 1, 1976--July 31, 1977. [HCN]

Description: Laser oscillation at 337 and 311 ..mu..m has been obtained from HCN molecules prepared in vibrationally excited states by the reaction between cyanogen radicals and hydrogen molecules. It has likewise been observed in HCN raised to an electronically excited state by flash photolysis. The characteristics of the pulsed output are quite different in the two cases and beginnings have been made on experiments to probe the pumping and energy transfer kinetics. The rate determining step is not the rea… more

Far infrared chemical lasers. Technical progress report No. 2, August 1, 1975--July 31, 1976

Description: A pumping mechanism has been found for the CO/sub 2/ gas laser which involves the transfer of electronic energy from O/sub 2/ (/sup 1/..sigma..g/sup +/) to CO/sub 2/, the oxygen dropping to the /sup 1/DELTA g state. This appears to pump vibrational states of CO/sub 2/ which are above the lasing state (001), and which most deactivate collisionally to (001) before the emission pulse. A pure rotational, diatonic OH laser has been discovered which is collisionally pumped from excited vibrational le… more
