Start resonator arrangement for phase-conjugated laser collector

摘要

The device uses several mirrors for the start resonator, which are arranged with respect to their condition and position, especially curve radius, in such a way, that several start resonators are formed which are stable in different ranges of the refraction of the active medium, whereby a large stability range is effectively covered with respect to the refraction, as it would be with the application of only one mirror for the start resonator. The mirrors used for the start resonator are preferably partially transmissive for the laser wavelength, and are arranged in series, so that the ray reflected at a special mirror can be partially transmitted through the other mirrors, and contributes thereby to the feedback in the resonator.
