Abstract:
A laser radiating optical system comprising:a laser light source that emits a laser beam having different vertical angles in mutually perpendicular first and second directions and having an uneven intensity distribution; a first shaping optical system including a first collimator lens that forms the laser beam exiting from the laser light source into a parallel beam with respect to the first direction and a first shaping element that converts the intensity distribution of the laser beam exiting from the first collimator lens with respect to the first direction and that simultaneously makes this laser beam converge at a convergence position, a predetermined distance away from the laser light source with respect to the first direction; and a second shaping optical system including a second collimator lens that forms the laser beam exiting from the laser light source into a parallel beam with respect to the second direction and a second shaping element that converts the intensity distribution of the laser beam exiting from the second collimator lens with respect to the second direction and that simultaneously makes this laser beam converge at a convergence position a predetermined distance away from the laser light source with respect to the second direction.
