Abstract
We report a new method for stabilizing the power of intracavity frequency-doubled multimode lasers with type I phase matching. Such lasers usually show strong fluctuations of the output power caused by coupling of longitudinal laser modes in the nonlinear crystal. We eliminate these fluctuations by placing the gain medium and nonlinear crystal in specific locations in the laser cavity where the nonlinear coupling of different longitudinal modes is strongly reduced.
