Abstract

A laser spectrometer scheme on the basis of an active interferometer containing saturated absorbing and amplifying media have been proposed. The form of nonlinear resonances in methane at a wavelength of 3.39 im was investigated with a resolution of about 12 kHz. The resonance amplitude in the active interferometer can exceed the amplitude in a similar passive system by one order of magnitude.
