LASER POWER STABILIZATION SYSTEM, AND METHOD AND DEVICE FOR ADJUSTING LASER POWER
Document Type and Number:
WIPO Patent Application WO/2020/097790
Kind Code:
A1
Abstract:
A laser power stabilization system (100), and a method and device for adjusting laser power. The laser power stabilization system (100) comprises: a laser resonant cavity (10), which comprises a mechanical adjustment device (101); a beam splitter (11); a power detector (12), which is used to obtain laser light beam-splitted by the beam splitter (11) so as to detect output power of a laser; and a controller (13), which is separately connected to the power detector (12) and the mechanical adjustment device (101). The controller (13) is used to obtain the output power and determine whether the output power complies with a preset standard output power. If not, an adjustment instruction is sent to the mechanical adjustment device (101) according to the output power so as to control the mechanical adjustment device (101) to perform an adjustment, so that the output power complies with the preset standard output power. When the problem of power reduction occurs, there is no need for intentional shutdown and maintenance, and self-recovery and adjustment are performed while the machine is in use. The entire process is automatically controlled without any manual adjustments, making power recovery faster and more accurate.
