Abstract
Disclosed is a solid state rod laser, monolithically integrated with a generator of optic frequencoes different from the emission frequency of the laser. The laser diode pumped solid state laser device has a rod, the seat of the laser effect, made of a nonlinear optic material, by doping with a rare earth, and includes an optic waveguide made in the mass of said rod of doped nonlinear optic material, parallel to the axis of the rod, said optic waveguide cooperating with means for changing the optic frequency of the laser beam. A preferred application is the obtaining of a laser frequency that is double the fundamental frequency making it possible, in the case of a neodymium laser, to obtain a green radiation, for example in digital optic disk readers.
