A laser emitting apparatus includes a detection and control system, a pump source, a first reflecting mirror group, a gain medium, and a beam deflection system on an optical path. The gain medium is pumped by the pump source to emit fluorescence, and is stimulated by resonance, between the first reflecting mirror group and a laser receiving apparatus, of the fluorescence to emit laser light. The beam deflection system emits the fluorescence or the laser light emitted by the gain medium, and emits the fluorescence or the laser light reflected by the laser receiving apparatus into the gain medium. The detection and control system adjusts the beam deflection system to preset emission angles, detects light intensities of the fluorescence or the laser light, and a light spot position of the laser light on the detection and control system, and adjusts the emission angle based on the light spot position.

Multi-Channels coherent beam combining (CBC) using a mechanism for phase and/or polarization locking that uses a reference optical beam and an array of optical detectors each detector being configured and located to detect overall intensity of an optical interference signal caused by interfering of the reference beam and a beam of the respective channel, where the fast intensity per-channel detection allows simultaneous and quick phase/polarization locking of all channels for improving beam combining system performances.
