Abstract:
A frequency-doubled diode pumped solid state laser with intracavity frequency doubling, comprising:a lasing solid state medium with reflecting coats which makes up a component part of a resonator cavity;at least one pumped light source constructed as a laser diode for generating suitable pumped light radiation;a frequency doubling nonlinear optical element in the form of a nonlinear crystal with reflective coatings which forms another component part of the resonator cavity; a resonator cavity being formed between reflective coatings of the solid state medium and of the frequency doubling element;optical means follow the pumped light source for conducting the pumped radiation to the lasing solid state medium;at least one aperture of thermally conductive material being provided at the frequency doubling element and/or at the lasing solid state medium; andsaid frequency doubling optical element being designed for phase matching at a higher temperature than the surrounding temperature.
