An optical resonator for stabilizing a laser source is useful for homodyne and heterodyne applications. The structural resonator length is considerably reduced by placing a laser source, such as a semiconductor laser (10) in an opening of an optical grating, whereby the laser beam is directed onto a parabolic mirror (15), which reflects the laser beam onto the grating (11). Thus, a "folded" beam path results.
