Abstract

Quasi-cw laser action with pulse duration up to 10 ms on the 1.59-, 2.45-micrometers atomic Cl transitions and 2.65-, 2.76-micrometers atomic O transitions was observed under uranium fission fragment pumping of atmospheric-pressure gas media. The mixtures of He, Ne, Ar with CCl₄, CHCl₃, CF₂Cl₂, C₂F₃Cl₃, O₂, NO, or CO were used. Nuclear pumping of high-pressure gas media at the 2.45- and 2.65-micrometers lines has been achieved for the first time. To our knowledge, the 2.76-micrometers line is a new laser line. The maximum energy parameters (output power of 130 W, power efficiency of about 0.2%) were measured for the 1.59-micrometers chlorine line in He/Ne/CCl₄ (25000/25000/1) mixture at 2 atm pressure. The minimum laser threshold was observed for this line at the thermal neutron flux of 2 X 10¹³ n/cm²s.
