ABSTRACT:
The invention relates to a method and device for frequency conversion, particularly for frequency doubling and particularly of continuous fixed frequency laser radiation, of semi-monolithic design with a ring resonator consisting of a mirror and an optically non-linear crystal. The objective of the invention is to develop a generic method and a device by means of which the frequency conversion, particularly the generation of the second harmonic from continuous fixed frequency laser radiation under avoidance of the disadvantages described, with high efficiency, with markedly enhanced opto-mechanical stability and a much simplified ease of production is assured, and is met by application of an electrical voltage to an annular piezo-adjuster 103 arranged between the mirror 101 and the crystal 102.
