The application will be described in detail below with reference to the drawings and implementations.

This application provides a high-power multi-module laser. Referring to FIGS. 1 to 3, the high-power multi-module laser includes a cabinet 1 and an optoelectronic module installed in the cabinet 1, a main control module 3 and a beam combining module 5.

Among them, the main control module 3 is installed on the outer wall of the installation box 2, and the combining module 5 is installed in the installation box 2.

One photoelectric module 4 includes one electric module 41 and at least two optical modules 42. Each optical module 42 is connected to the electric module 41, and each optical module 42 generates laser light under the drive of the electric module 41. That is, one electrical module 41 can drive two or more optical modules 42.

Compared with the prior art where each electric module needs to be provided with a control board, this application only needs one main control module 3 to realize power supply and control to the electric module 41 and the optical module 42 in each photoelectric module 4 . Therefore, when there are multiple optoelectronic modules 4 in the optoelectronic module, only one main control module 3, one beam combining module 5 and less electrical modules 41 need to be shared to achieve the output of 10,000-watt high-power laser.
