Paper Abstract

We present the stabilization of an intracavity frequency doubled blue Nd:YAG laser. A single stripe 1 W/808 nm laser diode was used for longitudinal end-pumping of a half- monolithic Nd:YAG/KNbO3 473 nm microlaser. A quarter- wave plate (QWP) was used inside the cavity to suppress the large amplitude noise. An adjustment of the QWP with a rotation angle of 45 degree(s) referring to the ordinary axis of the KNbO3 crystal resulted in a suppression of the noise in the blue laser emission.
