Shunt dodging system, laser device and gene sequencing system

The invention discloses a shunt homogenizing system which comprises a light splitting element, a first collimating and homogenizing element, a second collimating and homogenizing element and a light combining element. After incident light of multiple wavebands enters the light splitting element, the incident light is split into a first light and a second light; the first light is homogenized by the first collimating and homogenizing element to form third light, the second light is homogenized by the second collimating and homogenizing element to form fourth light, and the third light and the fourth light are combined by the light combining element to form target light. The invention further discloses a laser device which comprises a laser device and the shunt homogenizing system, and is used for homogenizing light emitted by the laser device. The invention further discloses a gene sequencing system. According to the invention, the technical problem of how to improve the uniformity of the target light comprisi
