The Optically Pumped Formic Acid Laser

  • Chapter

Abstract

Since the advent of optically pumped FIR lasers, the formic acid (HCOOH) has appeared as one of the most promising candidates for high efficiency FIR laser action. In fact some of its emission lines are among the most intense laser lines available in the far infrared region. Up to now more than 225 lines have been observed from HCOOH and its isotopic species that cover the region from 133.9 μm to 1730, 8 μm [1A–13A]. A remarkable point about the study of this laser is that it illustrates the original contribution of the spectroscopy of FIR lasers to the obtention of accurate molecular parameters. When the first observation of FIR laser action in formic acid was made, the only high resolution data available were provided by microwave spectroscopy of the ground and some excited states [1C - 3C]. From these data and some low resolution infrared spectra, it has been possible to assign some HCOOH emission lines and thus to get additional spectroscopic parameters [4C], Thereafter a high resolution infrared spectrum of the infrared bands pumped by the C02 laser has been recorded and assigned [1B].
