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.
