Optical pumping of the N2O-He and N2O-CO2-Hemixtures by a pulsed multifrequency HF laser for producing active media to amplify 10-mu m high-power ultrashort pulses

摘要

Optical pumping of the N2O-He and N2O-CO2 - He active media (at a total pressure of 1 atm) by similar to 1-mu s pulses from a multifrequency HF laser is studied with a view to use these media for amplifying a 10-mu m, 10(-12)-s ultrashort pulse (USP). Transitions forming the USP amplification band are determined, the energy stored in them is found, and the gains corresponding to maximum inversion in the medium are calculated.
