| 英文摘要 | Disclosed is a multibeam semiconductor laser array serving as a light source which is able to perform writing operations simultaneously by means of a plurality of laser beams. The multibeam semiconductor laser array includes a substrate; a plurality of semiconductor laser elements respectively provided on the substrate and drivable independently of one another; a fist window area disposed on a first end surface of a cavity forming the semiconductor laser elements, having a band cap wider than that of an active material layer of the semiconductor laser element, and not excitable electrically; a low reflectance coating applied to the first window area for reducing an optical reflectance; and a high reflectance coating disposed on a second end surface of the cavity forming the semiconductor laser elements for increasing the optical reflectance. According to the thus constructed multibeam semiconductor laser array, an optical cross talk can be eliminated, and a laser oscillation threshold value and a thermal cross talk can be minimized. |
