EMISSION-SPECTRUM OF AN ELECTRIC-DISCHARGE CLF LASER

Experiments revealed a complex structure of the emission spectrum of a n electric-discharge ClF laser corresponding to the D'-A' transitions with a maximum near 285 nm. The vibrational bands in the emission spec trum overlapped at the base in the range 282-286 nm because of a high pressure in the gaseous active medium. Theoretical calculations were m ade and an interpretation was provided of the vibrational structure of the emission spectrum of the ClF molecules. The emission spectrum of the electric-discharge CIF laser was shown to consist of the 0-4, 0 - 5, 0 - 6, 1 - 6, 1 - 7, and 2 - 8 bands of the D'-A' transition. A tot al efficiency of 0.1% was achieved for the first time for the CIF lase r and lasing was observed in a gaseous He - F-2 - BCl3 active medium.
