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.
