Abstract
The design philosophy and output radiation parameters of single frequency TEA CO2 laser with bleaching intracavity longitudinal modes selector (cell filled with SF6) are described. At cavity tuning to 10P(16) line and choosing optimum SF6 pressure in the cell the stable single frequency lasing is realized with scatter of radiation peak power in a series of “shots” less than ±7% of average value. The radiation energy density and intensity gradually tuned in the ranges 0.36–12.5 J/cm2 and 2.9–100 MW/cm2 correspondingly were realized in the focal plane of a lens with f = 127 mm.
