Abstract

The conditions for the formation of stable volume discharges at atmospheric pressure in CO₂–laser mixtures with an increased content of carbon dioxide and providing the generation of laser radiation pulses in the form of a "giant peak" with a base duration of up to 100 nanoseconds and a radiation energy of up to 1.5 J are determined. With the help of a selective resonator, a discrete rearrangement of radiation on individual vibrational–rotational transitions in the wavelength range of 9.2–10.8 μm is realized. The operation of the TEA–CO₂ laser at pulse repetition frequencies up to 50 Hz is ensured.
