Abstract

This paper presents the design and radiation characteristics of compact THz molecular laser with optical pumping for photoacoustic spectroscopy are reported. As a pump source, the compact CO₂ laser set in a pulse-periodic operation mode with radiation pulse power up of 100W is used. The wavelength tuning range of CO₂ laser is from 9.17 to 10.93 μm on the 92 emission line of ¹²C¹⁶O₂ molecule. Construction of the THz laser allows for switching between 3 different active mediums. Preliminary experiments showed the laser operating on 10 emission lines of methanol ¹²CH₃¹⁶OH with a wavelength range of 73-210 μm and a pulse power of up to 100 mW.
