Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to an adaptive drive device based on a corner cube coherent synthesis laser, which is applicable to the field of multi-channel laser drive and control. Background technique [0002] High-power lasers have important applications in the fields of scientific research, industrial processing, and military weapons. To achieve high-power lasers, most of them currently adopt the scheme of multi-channel laser coherent synthesis. In order to ensure the most concentrated output energy of the laser and avoid energy loss, many The synchronization of the laser beams is very important. In the actual application process, due to the influence of circuits, electronic components and other electromagnetic interference and other factors, it is very difficult to achieve absolute synchronization of multiple lasers. Therefore, there is a need for a device and method for synchronously driving mu...
