Intracavity Laser Spectroscopy (ICLS) is one of the most sensitive techniques of absorption spectroscopy. ICLS has a wide field of applications: molecular spectroscopy, spectroscopy of atmospheric gases and pollutants, investigation of chemical reaction's kinetics and nonlinear optical phenomena, such as stimulated Raman scattering, two- photon absorption, etc. The sensitivity of ICLS is limited by nonlinear processes in laser active media. The investigations of these processes permit achieving sensitivity of ICLS up to 10-11 cm-1.
