[0017] Depend on Figure 1-Figure 3 As shown, a red semiconductor laser 1, a green solid-state laser 2, and a blue semiconductor laser 3 are used to form a full-color laser light source, and the laser output power of the three lasers can be independently adjusted from 0 to full power. According to the principle of additive color mixing, the combination of different output powers of the three color lasers can be combined to output full-color lasers including white light.
[0018] A three-in-one bundled optical fiber 4 is made, and the core of the optical fiber is 400 microns according to the coupling efficiency requirements of the semiconductor laser and the solid-state laser and the optical fiber. The laser beam of the red semiconductor laser is coupled out through a coupling fiber 5 , and the laser beams of the green solid-state laser and the blue semiconductor laser are also coupled out through corresponding coupling fibers 6 and 7 . The other ends of the three coupled opti...
