Stimulated emission at 18.4μfrom a gasdynamic CO₂laser with electric-arc heating

Abstract

The recently obtained closed-form representation of the non-resonant thermonuclear reaction rate by a generalized hypergeometric function (Meijer's G-function) is used for a fusion yield calculation. A simplified physical model for the hydrodynamical processes in a fusion plasma compressed and heated by a laser-driven spherical shock wave permits calculation of the released fusion energy by integrating the thermonuclear reaction rate over the temperature. With the aid of the closed-form representation of the reaction rate this fusion energy production integral is approximation-free evaluated. After computing numerical factors. the approximate representation of the fusion energy yield given until now in the literature is compared with the more accurate ones obtained in this paper. and the apparent discrepancies are discussed.

CO2 laser oscillating in the range of 16 μm

“…The energy characteristics of a CO 2 laser at λ = 16 μm with optical pumping in the 4.3-and 9.6-μm bands were investigated [3]. Several investigations were directed at the production of oscillation in the range of ~14-18 μm between vibrational levels of so-called paired modes of the CO 2 molecule (03 [4][5][6][7][8]. Thus, the development of efficient lasers with emission wavelength in the range of 14-18 μm is of practical interest.…”
