Abstract: A laser includes a substrate and a resonant cavity. In addition to an active gain region, a first phase shift region, an optical branching region, and N reflective mode selection regions, the resonant cavity further includes a highly reflective surface, where a reflectivity of the highly reflective surface is greater than reflectivities of the N reflective mode selection regions, so that laser beams are output from the N reflective mode selection regions. Because the laser naturally includes at least two reflective mode selection regions, at least two laser beams are output. According to the laser provided by the embodiments of the present invention, one laser can output two laser beams or even multiple laser beams; therefore, laser beam generation efficiency is high and average costs for generating a single laser beam are accordingly reduced.

Abstract: This application provides a file sharing method and apparatus. The method includes: A first terminal device opens a to-be-shared target file, creates a file identifier and an index identifier of a mapping file in a distributed file system, generates, for a first distributed file service in the first terminal device, a first file descriptor that is used to access the target file in an open state and that is associated with the index identifier, and sends file sharing information including the file identifier to a second terminal device. The second terminal device opens the mapping file based on the file identifier in the file sharing information, and generates, for a second application in the second terminal device, a second file descriptor used to access the mapping file in the open state.
