Title:
DYNAMIC COUPLING CONTROL APPARATUS AND CONTROL METHOD FOR LINEAR COMPENSATION OF HIGH-POWER OPTICAL FIBER LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/224312
Kind Code:
A1
Abstract:
Disclosed are a dynamic coupling control apparatus and control method for linear compensation of a high-power optical fiber laser device. The dynamic coupling control apparatus comprises a power supply control system, a large-diameter optical fiber laser system and a dynamic coupling control system. The dynamic coupling control system dynamically couples a control system of the large-diameter optical fiber laser system under the control of an algorithm, so that a stable linear output of a large-diameter optical fiber and a laser effect width are enhanced, and this can also ensure that the number of eigenmodes inside the optical fiber does not increase even if the diameter of the optical fiber is excessively large, thereby improving the light beam quality of an output light beam. The laser effect width of an optical fiber laser device can be enhanced, thereby improving the precision of linear collimation of the laser device; and the number of eigenmodes inside an optical fiber can be reduced by means of a dynamic coupling method, thereby improving the light beam quality.
