Laser generating device with visible light

The invention belongs to the technical field of laser, and particularly relates to a laser generating device with visible light. The laser generating device comprises a glass laser tube, an indicating light generator, an optical lens and an optical axis adjusting structure; light emitted by the glass laser tube is invisible light; the light emitted by the indicating light generator is visible light; the optical axis adjusting structure is used for adjusting the position of the optical axis of the glass laser tube, so that emergent light of the glass laser tube and emergent light of the indicating light generator after passing through the optical lens are coaxial and in the same direction after passing through the optical lens; according to the laser generating device with the visible light, the glass laser tube is adopted as a laser source, the fixing mode of the glass laser tube is changed by combining the appearance structure characteristics of the glass laser tube, and the position of the glass laser tube
