LASER ENERGY MANAGING DEVICE AND METHOD, ADDITIVE MANUFACTURING SYSTEM

Abstract:

A laser energy managing device comprises: a laser beam splitting device, at least one micro-bending device, and a controller. The laser beam splitting device is configured to split an input laser beam from a laser generator into a plurality of split laser beams, and comprises a plurality of split transmission channels configured to transmit the plurality of split laser beams respectively. The at least one micro-bending device is configured to micro-bend the split transmission channels to attenuate corresponding split laser beams transmitted thereby and thus obtain a plurality of output laser beams. The controller is configured to control a micro-bending degree of each split transmission channel.
