Population inversion by mixing in a shock tube flow

A steady-state population inversion high enough to sustain laser action has been generated by thermal pumping through the mixing of CO 2 into supersonic N 2 flow in a shock tube. Continuous lasing at 10.6 μ with an optical cavity, oriented transversely to the mixed flow in a nozzle has been obtained...

Description
Summary:A steady-state population inversion high enough to sustain laser action has been generated by thermal pumping through the mixing of CO 2 into supersonic N 2 flow in a shock tube. Continuous lasing at 10.6 μ with an optical cavity, oriented transversely to the mixed flow in a nozzle has been obtained with a power output of 50 W during 1–2 msec. Optimal operating conditions are discussed.
