摘要：device for stabilizing the wavelength of a laser diode in the air (1) for a technicallongim\étrie in the interferometer waveguides.in order to stabilize the wavelength inair, an interference phenomenon, after young) is produced and detected in an air

chamber of constant length and stable with two light waves of a beam spot is consistent.the point like light waves are formed by the ends (3a, 4a) of the wave guides (3, 4).thephoto detectors (8a, b), and a control device (13), the frequency of the laser diode (1), sothat the interference phenomenon, and therefore the wavelength in air, remained withinthe reference area. the arrangement is simple and compact.
