英文摘要	The laser diode (11) of the electro-optical device (10) is frequency-controlled with the aid of a control module (40) comprising a rubidium cell (41) and an optical sensor (42), as well as a further module (43) for controlling the injection current and/or the temperature of the laser diode. A controlling light beam (18) is conveyed by means of a multi-mode optical fiber (14) to the rubidium cell. The optical sensor measures the intensity of the light beam transmitted by the rubidium cell and supplies a signal used by the further module for regulating the injection current and/or the temperature of the laser diode so as to stabilize the frequency of the light (16) emitted. The optical fiber is coupled to the laser module in such a way as to collect part of the light (16, 21) emitted by the front face of the laser diode and reflected by a lens (12) in front of the laser diode. The diode-lens assembly is heat controlled. Feedback in the laser diode and the power supplied to the laser diode are reduced, and the control device is simplified. The device finds application particularly in interferometry, atomic frequency oscillators, spectroscopy, and fiber optics data transmission.
