Tuning characteristics of a high pressure CO2 laser pumped CH3F Raman laser
Abstract
A laser system consisting of a two-stage, 20 atmospheres CO2 laser and a CH3F Raman laser for tunable generation of far-infrared radiation is described. For CO2 laser scanning over the 9R emission branch, frequency tuning over intervals which cover 70 percent of the frequency range between 23/cm and 45/cm is reached. A measurement at fixed-CO2-laser pulse energy shows that the far-infrared pulse energy varies strongly with frequency. In the emission peaks, a photon conversion efficiency of the order of 0.1 is obtained.
