Abstract:

The method of intracavity laser (ICL) spectroscopy, proposed in 1970, became one of the most striking applications of lasers, in which the multimode laser is a nonlinear detector of weak absorption with a very large effective length of the absorbing layer, reaching 1.8 Ч107 m. Today, BP-spectroscopy is one of the most sensitive methods of spectroscopy, widely used for research of the traditional tasks of spectroscopy, and new challenges that can not be solved by other methods. The high sensitivity of the method to the absorption and the amplification, broad spectral range, simplicity of design, and a small volume of the medium allow us to study gases and vapors with variation of external conditions. This paper presents the analysis of intracavity spectroscopy, occurred in 40 years. The paper lists the requirements on the laser of ICL-spectrometer, describs the chronology of the method, which was developed in parallel with the development of lasers. A review of numerous applications of BP-spectroscopy, including spectroscopy of overtones, spectroscopy of excited molecules, and analytical application of the method is presented.
