Abstract
Provided is a laser optical path system, including: a laser, a beam combiner, a loop guide assembly, and a fluorescence assembly; wherein a light beam emitted by the laser includes a first light beam passing through the first region and irradiating to the fluorescence assembly, wherein the fluorescence assembly generates a fluorescence upon excitation of the first light beam, and the fluorescence is reflected to the second region by the fluorescence assembly, and is further reflected into a direction towards a light outlet by the second region; and the light beam emitted by the laser further includes a second light beam reflected to the loop guide assembly by the first region, wherein the second light beam is further reflected to the first region by the loop guide assembly, passes through the first region, and irradiates to the direction towards the light outlet in synchronization with the fluorescence.
