New emission lines of a CH3OH laser pumped by CO2 laser radiation

A new absorption line of the CH₃OH vapor, which coincided with the R(38) line of the 00⁰1–10⁰0 band of the CO₂ laser, was detected and investigated in the course of a study of an optically pumped CH₃OH laser. The absorption coefficient was 0.1 cm^–1 · torr^–1. Pumping with the R(38) line produced submillimeter radiation of wavelengths 164, 246, and 470 μ and of output power 0.1–1 mW.
