Abstract

Intra cavity laser spectroscopy which is effective and simple in creation has been proposed and studied. The method may be used in systems where the longitudinal relaxation time is considerably greater than the pump pulse duration. It is based on the possibility both of essential increase of the laser pulse duration and of its control over a large range. In the experiments with Al₂O₃:Ti³⁺ laser the additional increase in sensitivity was equal to 10² - 10³ as compared with conventional absorption spectroscopy. The sensitivity control interval was equal to 10^-5 - 10^-6 sm^-1. The basic peculiarity of the proposed method is the application of the special receiver signal processing for the elimination of the influence of the laser pulse energy (duration) high fluctuations.
