Abstract
Arrangements are disclosed for reciprocatively scanning a focused laser beam across an optical frequency converting crystal while deriving an output laser beam at the converted frequency along a stationary path. An effective elongated illumination pattern is provided for the crystal which reduces thermal gradients across the crystal, while the beam density at the crystal is sufficiently large so that high conversion efficiency may be realized.
