摘要
The output beam parameters of the disk laser were investigated at different pump powers of nine-beam spatially periodic pumping and different resonator lengths. It was realized that a super-mode lasing regime and the values of thermally-induced distortions of an active disk were measured. The diffraction-limited output beam parameters came from the total aperture of all the lasing spots. An explanation of the in-phase super-mode lasing conditions was proposed, and the limits of its operation were defined.
