Abstract
An optically pumped cw 10.6‐μm DF/CO2 transfer laser has been demonstrated. This has been accomplished by exciting a 3 cm × 0.3 cm transfer laser medium, consisting of a 1 : 19 : 80 DF/CO2/He flowing gas mixture at 22 torr and room temperature, with a 70‐Watt multiline chemical DF laser. In the preffered ’’intracavity’’ configuration where the transfer‐laser medium was located in between the DF‐laser resonator mirrors, 1.5 W of 10.6‐μm power was outcoupled. This power corresponds to a photon conversion efficiency of available DF‐pump flux to outcoupled transfer‐laser flux of 6%. Analysis predicts that multiline DF laser‐to‐single‐line CO2 photon conversion efficiencies exceeding 90% should be attainable in an optimized apparatus configuration.Keywords
