Abstract
In a laser arrangement and a method for generating a multimode operation with intracavity frequency doubling, the object of the invention is to eliminate fluctuations in output caused by the nonlinear coupling between the longitudinal modes due to sum frequency generation in a simple laser construction which has increased thermal and mechanical stability. Two multimode spectral regions are situated in the edge areas of the spectral gain region of a disk-shaped gain medium within which longitudinal modes have no gain advantage among one another for spatial hole burning, and in which oscillation of one of the two multimode spectral regions is prohibited.
