NCL(B) Based Short Wavelength Chemical Laser

Abstract

Based on the results of this work, the prospects of development of a visible chemical laser based on NCl(b) are promising. NCl, in the electronically excited b-state emits to the ground state at 665 nm. The NCl b-state is generated by energy-pooling of NCl(a) and excited iodine atoms I*. All of these species can be generated from chemical reactions solely. This work has shown that: (1) In the generation of NCl, the branching ratio for NCl(a) is high. 65% of the HN3 ends up in the NCl(a) state; (2) The rate constant for the energy- pooling reaction NCl(a) + I NCl(b) is quite favorably large, approximately 10-11 cu cm/sec; (3) A gain on the order of 1x10(exp 4)/cm was obtained; and (4) Variations of the cavity ring-down experiment showed that virtually no NCl(x) is formed via reaction
