POTENTIAL LASER ACTION IN A FLAME

Abstract

A continuous sheet of flame, i.e., a region where chemical reaction and excitation takes place was developed. This region is two inches wide and is several feet in length and operates at very low pressures where collisional de- excitation decreases greatly. The by-products of the flame are then expanded and pumped out. The flame itself is a few centimeters in thickness and the pressure across it remains constant. However the pressure decreases as one approaches the vacuum pump input region. The potentialities of chemical excitation in this form has not yet been fully investigated. However, a region in the form of a long strip where intense chemical reactions take place at very low pressures, i.e., about 1/200th of atmospheric pressure has been confined. Out of the heat of combustion released, it is highly probable that some of the energy will be exciting some of the vibrational levels of the by-products.
