Abstract

A simple relationship is derived between Lc the critical length for amplified spontaneous emission, and LT, the threshold length of gas that must be excited for laser action to occur in a cavity of loss delta l. The relationship is experimentally verified and the semiclassical laser theory of Stenholm and Lamb is re-verified in a new way.
