| Popis: | Optical pumping of the N2O—He and N2O—CO2—He active media (at a total pressure of 1 atm) by ~1-μs pulses from a multifrequency HF laser is studied with a view to use these media for amplifying a 10-μm, 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. |
