Abstract

A high power laser array parallel output adjustment device comprises a laser array, an adjustment module, a focus lens, a high reverse lens, an image detector and data processing equipment, wherein the image detector is connected to the data processing equipment, and the adjustment module is configured to adjust the attitude of the laser array. The high power laser array parallel output adjustmentdevice provided by the invention adjusts the posture of the laser array by the adjustment module such that the output laser of the end cap is coincident at the focus of the back focus of the lens, can realize parallel output of the high power laser array, and is used for making up the expensive cost of the existing adjustment device, the complicated data processing and working only at a low powerlaser, and solving the problem of quickly adjusting the parallel output of high power laser arrays.

Description

technical field [0001] The invention relates to the field of high-power laser instruments, in particular to a high-power laser array parallel output adjustment device and adjustment method. Background technique [0002] High-power parallel laser output arrays are the basis for the field of spatial beam combining. In the low-power field, the parallelism of laser beams can be measured by interferometric methods, and whether the beams are parallel can be judged by observing the interference fringes of the two beams. Based on this principle, the Chinese Invention Patent No. ZL201110211062.3 proposes a lower power laser beam adjustment parallel system, which includes a laser probe, a carrying platform, a scale plate and a computer system, and performs feedback adjustment by calculating the difference in spot coordinates. This method does not withstand high laser power, expensive instruments, and complicated data processing. Therefore, the development of a high-power laser array...
