Effect of self-adjustment in organic dye lasers
Abstract
The kinetics of spectrum formation is studied for a rhodamine-6G laser pumped by a flash lamp. It is shown that, regardless of the excitation energy, the maximum spectrum width occurs at the initial moment; 100 msec later, the maximum emission intensity shifts rapidly toward the short-wave region, the frequency band decreasing in the process. This is followed by smooth displacement of the lasing band toward the long-wave region, with subsequent stabilization of both the bandwidth and spectral position. An interpretation of this behavior is proposed for an organic dye laser. In particular, the long-wave shift is attributed to selective directional propagation of laser beams (with minimum losses) in an optically inhomogeneous medium produced by pumping (effect of self-adjustment).
