Abstract

The pumping power dependent locations of the degeneration points were calculated for a plane-concave cavity. Such a simple experimental method for determining the degeneration points and their shifts due to thermal lensing is proposed. The laser beam patterns near the degeneration points were observed. For the pumping configuration under investigation the beam parameter product at the degeneration points increases considerably.
