A solid state laser apparatus capable of suppressing a mode hopping phenomena by restricting longitudinal modes except a fundamental mode, and providing a very stable output. The solid state laser apparatus comprises such components as a semiconductor laser emitting a pumping radiation for exciting a lasant material, lens systems for focusing the pumping radiation and an optical resonator comprising a concave mirror, the lasant material formed of Nd:YVO4 doped with approximately 1% of Nd and a non-linear optical element formed of KTiOPO4 with an inclined c-axis.

L'invention est un appareil laser à semi-conducteur capable de supprimer un phénomène de saut de mode en bloquant les modes longitudinaux, à l'exception du mode fondamental, et de produire un signal de sortie très stable. Cet appareil comprend un laser à semi-conducteur qui émet un rayonnement de pompage pour exciter un matériau actif, un système de lentilles servant à concentrer le rayonnement de pompage, et un résonateur optique comportant un miroir concave, le matériau actif étant constitué de Nd:YVO4 dopé avec environ 1 % de Nd et d'un élément optique non linéaire de KtiOPO4 à axe c incliné.
