Abstract
A device for frequency conversion of a first laser beam generated with a first frequency. The device has a first crystal for generating a second laser beam having a second frequency, which differs from the first frequency. The second laser beam propagates parallel to the first laser beam after leaving the first crystal. A second crystal, which generates from the first and second laser beams a third laser beam having a different third frequency. An optical deflection device influences the relative beam position between first and second laser beams such that the first and second laser beams, before entering into the second crystal, propagate at an angle with respect to one another, which angle differs from zero, and enter in a manner spaced apart from one another at an entrance surface of the second crystal and intersect within the second crystal with at the same time collinear phase matching.
