Control system and method for multi-path laser transmission of laser device

The invention discloses a control system and method for multi-path transmission of a laser device. The method includes setting a first fixed holophote, a second fixed holophote and a mobile holophote. The mobile holophote is used for changing the light path of a laser output by the laser device: after being reflected by the second fixed holophote, when the mobile holophote is in a lower position, a reflected laser of the laser output by the laser device is output from a first light path after being reflected by the first fixed holophote; while when the mobile holophote is in an upper position, the reflected laser of the laser output by the laser device is output from a second light path after being reflected by the mobile holophote, so that the multi-path laser transmission is achieved. The control system and method for multi-path laser transmission of the laser device solves the problem that the existing energy light splitting technology cannot achieve the high-power multi-path laser transmission; by being combined with advantages of time-sharing and laser-splitting technology, can guarantee the multi-path laser transmission under the high-power premise; and can carry out targeted designs according to actual production states, so that working efficiency and cost performance are enhanced, processing technology is improved, and cost is saved.
