Abstract

High power diode pumped solid-state lasers with second harmonic generation (SHG) offer compact, efficient and reliable visible light sources that may substitute less efficient gas lasers in medical applications and for the excitation of secondary laser sources. Most solid-state lasers however exhibit instabilities caused by optical nonlinear dynamics and the build up of the thermal lensing in the laser crystal when pumping power is changed rapidly.
