Third diffusion component on the emitting light path of the third shrink beam component is set, for being emitted to the third laser source The first primary lights be scattered again after shrink beam and eliminating coherence is handled and is emitted;
Third relay lens assemblies on the emitting light path of the third diffusion component are set, for the third laser source First primary lights of outgoing collimate after scattering and eliminating coherence processing and are transmitted to second beam splitter transmission outgoing, and described The reflection emitting light path of second beam splitter realizes light combination;
The second optical filter on the reflection emitting light path of second beam splitter is set, for filtering out second beam splitter Reflection outgoing light in stray light to be emitted the first primary lights and third primary lights;And
The second relay lens assemblies on the emitting light path of second optical filter are set, the third laser source is used for transmission The first primary lights and second primary lights of outgoing;
Wherein, the light-integrating subassembly includes:
The friendship of the emitting light path of first relay lens assemblies and the emitting light path of second relay lens assemblies is set The 4th beam splitter on crunode for receiving second primary lights and reflect penetrating, and receives and is transmitted to a light Second primary lights of road and the first primary lights of third laser source outgoing simultaneously transmit and penetrate and transmit outgoing Direction is identical as reflection exit direction, so that three primary colours light synthesizes white light and is emitted;
Collector lens group on the emitting light path of 4th beam splitter is set, for the white light of synthesis to be focused and is emitted; And
Optical wand on the emitting light path of the collector lens group is set, and the entrance port of the optical wand is located at the collector lens group Focus on to receive the laser beam that the collector lens group focuses.
