The invention provides a laser scanning device and a laser radar, the laser scanning device comprises a laser source and a lens group, the laser source is used for emitting scanning light rays, and the lens group is arranged on an emitting path of the scanning light rays and is used for adjusting the emitting direction of the scanning light rays and enabling the scanning light rays to be emitted in parallel. According to the invention, the lens group is arranged on the emission path of the laser source, so that the scanning light emitted by the laser source is emitted in parallel along the preset direction, and the point cloud density of the scanning light in the area near the to-be-measured target is adjusted, so that the laser scanning device is not limited by the measurement distance in the process of scanning the long-distance to-be-measured area, and the measurement accuracy of the to-be-measured target is improved. The measurement precision and accuracy of the laser scanning device on a long-distance me
