(12CO2+ 13CO2+ 14N2O+ 15N 14NO)-active media of high pressure with optical pumping by HF laser radiation

Numerical and experimental study of processes of absorption of pumping radiation of HF-laser, a laser oscillation and a radiation amplification in a (CO 2 +N 2 O) active medium of high pressure is carried out. Measurements and numerical estimation of an absorption coefficient for 21 spectral lines of the HF-laser radiation, which are strongly absorbed by the CO 2 and N 2 O molecules, are performed. Measurements of an integral absorption coefficient for total pumping spectrum for the laser media of various content are carried out. About 63 and 35 % of radiation of the non-chain and chain chemical HF-laser, respectively, are absorbed using a four-component laser mixture. For the mono-component active media the maximum specific energy of an output radiation in 10 microns region, efficiency of an energy conversion and a small signal gain ( 12 CO 2 - 200 J/l, 18 %, 9 m -1 ; 14 N 2 O - 100 J/l, 7 %, 6 m -1 ) are obtained. For two-component ( 12 CO 2 + 14 N 2 O)-active media these parameters are 120 J/l, 7%, 7 m -1 at maximum laser energy 12 J. According to the numerical estimation, a coefficient of conversion of energy accumulated in lasing mode to energy of a pico-second pulse in 10.6 micron region for mixture of the CO 2 and N 2 O molecules may achieve 30 %.
