Abstract
Provided is a light source device, including a first laser light source group, a second laser light source group, a dichroic mirror, a fluorescence converter, and an emission component. The first laser light source group emits laser light of a first waveband, and the second laser light source group emits laser light of a second waveband and laser light of a third waveband. The dichroic mirror is disposed on light-output sides of the first laser light source group and the second laser light source group, and the fluorescence converter and the emission component are respectively disposed on light-output sides of the dichroic mirror. The dichroic mirror is configured to emit laser light of various wavebands, and the fluorescence converter generates target fluorescence under the excitation of the laser light of the first waveband, and the target fluorescence is reflected by the dichroic mirror to the emission component.
