Intracavity frequency doubled solid state laser that emit light in the visible spectral range have great potential for technical applications. These diode pumped lasers are compact, robust, efficient and have a higher output power compared to laser diodes. The intracavity frequency conversion by the optical nonlinear crystal is highly efficient but on the other hand destabilizes the dynamic of the laser under multimode operation. The resulting periodic or chaotic fluctuations of the output intensity are known as the green problem in literature and limits the technical applicability of such a kind of laser. However, it is possible to suppress the intensity fluctuations of the laser, but all proposals are based on optical modifications to the laser cavity.
