โœฆ Synopsis

The use of a ribbon burner resulted in 3 100 fold laser power enhancement from a CT'&-02 free burning '&me. ?Z'he $eect of He, SFB, X20, CO, COz, N,, SO?, and NO2 on laser power was examined. The hi&e% power. 0.6 W, was achieved from 3 mixture of CS1, 02, and I&O at flow rates of 3.9;7 10, tid 7.6 millimoteslsec, respectively.

A flame laser is an example of a purely chemical laser. On the basis of a simple madei its existence was predicted ia 1965 by Bleekrode and Nieuwpoort 11).

As a Tesult of a study of the chemiluminescence from a CS,, O,, N, flame, Faster and KimbeN 123 re-

## A chemical laser has been constructed in which simultaneous output is obtained from both CO and CO2 laser species at 5 and 10 Mm, respectively. Excitation of CO2 is via energy transfer from vibrationally excited CO (CO?) produced in the photolytically initiated reaction: 0 + CS + CO? + S. G am

The laser-induced desorption of CO adsorbed on an epitaxiahy grown film of Cr203 ( 111) has been studied using 193 nm ( 6.4 eV) laser light. The velocity flux distributions of the desorbing neutral CO in its ground electronic state were recorded quantum state speciticahy by making use of a (1 + 1')
