Abstract:
Results are presented of an experimental investigation of an infrared laser utilizing IBr–CO2 and Br2–CO2 mixtures pumped by electronic-vibrational coUisional excitation transfer from electronically excited Br*(42P1/2) atoms to Raman vibrational states [(1001)–(0201)] of the CO2 molecule. It is shown that, under conditions of broad-band flash photolysis, the IBr molecule is a more efficient supplier of Br*(42P1/2) atoms than Br2·As a result, simultaneous three-frequency laser action at wavelengths of 2.7 μ (42P1/2→42P3/2 transition in atomic bromine), 4.3, and 10.6 μ (vibrational–rotational transitions in the CO2 molecule) was obtained from an IBr–CO2 mixture. On the other hand, laser action was only obtained at 10.6 μ from a Br2–CO2 mixture. A qualitative laser model developed showed satisfactory agreement with the experiment.
