ABSTRACT:
A solid state laser apparatus is capable of suppressing a mode hopping phenomena by restricting longitudinal modes except a fundamental mode, thereby providing a very stable output. The solid state laser apparatus includes such components as a semiconductor laser emitting a pumping radiation for exciting a lasant material, a lens systems for focusing the pumping radiation and an optical resonator including a concave mirror. The lasant material may be formed of Nd:YVO.sub.4 doped with approximately 1 at % of Nd and a non-linear optical element may be formed of KTiOPO.sub.4 with an inclined c-axis.
