Title:
LASER SYSTEM AND LASER DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/184857
Kind Code:
A1
Abstract:
A laser system and a laser driving method. The laser system may comprise: a main control chip (110); a laser emitter (100), wherein the laser emitter (100) has a reference laser power value; a laser driving circuit (120), which is connected to the main control chip (110) and the laser emitter (100), wherein the laser driving circuit (120) is used for adjusting an actual laser power value of the laser emitter (100) according to a PWM signal value, which is transmitted by the main control chip (110); and an optical power measurement apparatus (20), which is used for measuring the actual laser power value of the laser emitter (100), wherein the main control chip (110) is used for adjusting the PWM signal value, according to the relationship between the actual laser power value, which is measured by the optical power measurement apparatus (20), and the reference laser power value, which is outputted by the main control chip, so that the actual laser power value of the laser emitter (100) is equal to the reference laser power value.
