Abstract
A laser beam transmission apparatus comprises a light-incidence optical system () converging and focusing a laser beam emitted from a solid-state laser apparatus (), and an optical fiber () which transmits the laser beam that has been converged and focused by the light-incidence optical system. The light-incidence optical system () has at least first and second lenses () disposed on the same optical path. A first distance (a) between an output end of the solid-state laser apparatus and the first lens or a second distance (b) between the second lens and a light-incidence end of the optical fiber is freely set according to a relational formula based on a focal distance (f, f) of each of the first and second lenses.
