| 英文摘要 | The device adapted to regulate the light power emitted by a laser diode (2) associated to an electric supply circuit (32) comprises a photosensor (6) providing an electric signal representing the mean optical power of the laser diode. A circuit (8) associated to the photodetector provides an error signal representing the deviation between the actual light power and an order power. The error signal is applied to a circuit (10) which controls a Peltier element (22) for cooling the laser. The supply circuit (32) either uses constant current or is controlled by a safety branch (30) which is operated in case of a sudden temperature variation or failure of the main servo control. The device may be particularly used in telecommunications. |
