Theoretical investigation of the dynamics of stimulated emission and characteristics of a pulsed CO laser with selection of lines suitable for isotope enrichment

A theoretical investigation is made of the output pulse duration and the efficiency of a CO laser pumped by ~1 μsec pulses. A study is also made of the selection of the P₉(J) and P₁₀(J) lines suitable for laser isotope enrichment. The variable parameters are the pressure and temperature of the gas, pump energy density, losses in the resonator, and losses at the selected transition line.
