Abstract

A laser source includes a light-emitting assembly, a converging lens group, a phosphor wheel and a combining component. The light-emitting assembly is configured to emit a laser beam. The converging lens group is configured to converge the laser beam emitted by the light-emitting assembly. The phosphor wheel includes a fluorescence-exciting region and a laser-reflecting region. The fluorescence-exciting region is configured to generate a fluorescence beam with a color different from the converged laser beam under an excitation of the laser beam. The laser-reflecting region is configured to reflect the converged laser beam to the converging lens group. The combining component is disposed between the light-emitting assembly and the converging lens group. The combining component is configured to reflect the fluorescence beam excited by the phosphor wheel and the laser beam reflected by the phosphor wheel to a beam outlet of the laser source.
