The possibility of a CW laser with a radio-isotope pumping source
Abstract
Results are presented of studies of a quasi-CW low-threshold laser (2.03 and 2.65 microns) using the Ar-Xe mixture and excited by uranium fission fragments. For an Ar:Xe mixture of 100:1 at a pressure of 0.24 atm the lasing threshold at 2.03 microns is achieved at a thermal neutron flux density of 1.5 x 10 exp 12/sq cm s, which corresponds to a specific pumping power about 0.02 W/cu cm. The possibility of the pumping of this laser by alpha particles from radio-isotope sources of Pe-210 and Cm-242 is shown.
