Filed: 2002-01-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a device for lengthening a laser beam which can further lengthen a beam cross section of the laser beam.  <P>SOLUTION: A laser source emits a laser beam. The laser beam emitted from a laser source is injected to an optical waveguide member. An optical waveguide member has an incident surface whereto laser beam emitted from a laser source is injected, a scattering surface and an emission surface. The laser beam, injected from the incident surface, propagates inside an optical waveguide member and is scattered in a scattering surface. A scattered light is emitted to an outside from an emission surface. An emission source has a shape which is long in one direction. The optical waveguide member has a plate-like waveguide structure, which guides scattered light scattered in a scattering surface to an emission source. The waveguide structure gradually becomes thinner toward the emission surface starting from the scattering surface.  <P>COPYRIGHT: (C)2003,JPO
