Light transverse mode control system and light transverse mode conversion control method

The invention provides a light transverse mode control system and a light transverse mode conversion control method and relates to the laser system. The system comprises an initial condition control module, a boundary condition control module and a controller, wherein the controller is connected with the initial condition control module and the boundary condition control module, the controller is used for sending a first signal to the initial condition control module according to initial conditions so as to convert a light field in an original mode into a light field in an intermediate mode, and the controller is further used for sending a second signal to the boundary condition control module according to boundary conditions so as to convert the light field in the intermediate mode into a light field in a target mode. The system is advantaged in that loss of light in a light mode control conversion process can be made to be relatively low, and the system is applicable to actual application. 本发明提供种光横向模式控制系统及控
