Abstract
The invention relates to a laser oscillator for simultaneously or alternately producing several wavelengths. A tunable laser-active medium (3) is placed between several cavities or resonators (4; 1a, 1b . . . 1n). The resonators (4; 1a, 1b . . . 1n) are geometrically coupled by a polygonal prism (2), which allows a simultaneous operation or, by rotation of the prism (2) or some other movement of a beam deflection, an alternating operation.
Claims17
A multi-wavelengths laser oscillator with geometrically coupled resonators having a first mode for a simultaneous production of several wavelengths and a second operating mode for an alternating production of several wavelengths, and comprising an active medium, which emits in one emission mode on several discrete wavelengths and in a second emission mode emits a continuous spectrum and is inserted between several resonators, the alternating production being effected by rotation of polygonal prism, comprising said resonators are geometrically coupled to unfixed polygonal prism in such a way that at least on one edge and two surfaces of the polygonal prism for the realization of said simultaneous production.
