LASER EMITTING APPARATUS, LASER EMITTING METHOD AND LASER WIRELESS CHARGING SYSTEM

A laser emitting apparatus (41), a laser emitting method, and a laser wireless charging system are disclosed. The laser emitting apparatus (41) includes: a detection and control module (414, 415), a pump source (411), and a first reflecting mirror group (413), a gain medium (412), and a beam deflection module (416) that are disposed on an optical path. The gain medium (412) is pumped by the pump source (411) to emit fluorescence, and is stimulated by resonance, between the first reflecting mirror group (413) and a laser receiving apparatus (42), of the fluorescence to emit laser light. The beam deflection module (416) emits the fluorescence or the laser light emitted by the gain medium (412), and emits the fluorescence or the laser light reflected by the laser receiving apparatus (42) into the gain medium (412). The detection and control module (414, 415) adjusts the beam deflection module (416) to a plurality of preset emission angles, detects light intensities of the fluorescence or the laser light at the plurality of preset emission angles, and a light spot position, of the laser light, on the detection and control module (414, 415), and if the light intensity is greater than a first threshold at any preset emission angle, adjusts the emission angle of the beam deflection module (416) based on the light spot position, so that a range in which the laser emitting apparatus tracks the laser receiving apparatus (42) is expanded in the field of wireless charging.
