Title:
OPTICAL FIBER LASER, LASER RADAR, OPTICAL POWER ADJUSTMENT METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/160570
Kind Code:
A1
Abstract:
The present disclosure provides an optical fiber laser, a laser radar, and an optical power adjustment method, applicable to the field of laser radars. The optical fiber laser comprises: a plurality of seed light lasers having different powers and an optical fiber amplifier. The plurality of seed light lasers are the same type of lasers; one of the seed light lasers is configured to: enter an excitation state in response to a trigger event and transmit a first seed light signal; and couple the first seed light signal to the optical fiber amplifier. The other seed light lasers in the seed light lasers are configured to be, in response to the trigger event, in a state to be excited. The optical fiber amplifier is configured to be always in a gain saturation state and amplify the first seed light signal.
