Paper Abstract

A promising candidate for a visible-wavelength chemical laser is the NCl molecule in the b1(Sigma) electronic state, emitting at 665 nm. This state can be generated by purely chemical methods. The energy-pooling reaction, NCl(a1(Delta) ) + I*(P1/2) yields (b1(Sigma) ), is estimated to have a rate coefficient of 1 X 1011 cm3/sec from a steady-state approximation. Experiments using a high speed flowtube have shown that NCl(a1(Delta) ) is generated in high yield via the reaction of HN3 with chlorine atoms. The measured yield is 65%. Preliminary measurements of gain were initiated employing the cavity ring-down technique. These experiments indicate that gain may be present under the operating conditions used. Confirmatory experiments are in progress.
