Title:
LASER EMITTING APPARATUS, LASER EMITTING METHOD AND LASER WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/088774
Kind Code:
A1
Abstract:
A laser emitting apparatus (41), a laser emitting method and a laser wireless charging system. The laser emitting apparatus (41) comprises: measurement and control modules (414, 415), a pumping source (411), and a first reflector group (413), a gain medium (412) and a light beam deflection module (416), which are arranged on a light path. The gain medium (412) is pumped by the pumping source (411) to emit fluorescent light, and excited fluorescent light resonates between the first reflector group (413) and a laser receiving apparatus (42) to emit a laser. The light beam deflection module (416) emits the fluorescent light or laser emitted by the gain medium (412) and emits, into the gain medium (412), the fluorescent light or laser reflected by the laser receiving apparatus (42). The measurement and control modules (414, 415) adjust the light beam deflection module (416) to a plurality of preset emission angles, measure the light intensities of the fluorescent light or laser at the plurality of preset emission angles and light spot positions of the laser on the measurement and control modules (414, 415), and adjust, if the light intensity at any preset emission angle is greater than a first threshold value, the emission angle of the light beam deflection module (416) according to the light spot position, such that the range of the laser emitting apparatus tracking the laser receiving apparatus (42) is expanded in the field of wireless charging.
