<p><P>PROBLEM TO BE SOLVED: To realize high-output application by controlling the reflected part of a radiated light beam to guide it in any desired direction. <P>SOLUTION: A radiated light beam from a radiation source is at least partially reflected by a partial reflection element which is inclined at a small angle to the optical axis of an input light beam so as to reflect part of the radiated light beam to a transmissive element disposed close to the radiation source. Consequently, reflective attenuation is reduced or eliminated and polarization-depending loss is optimized without making a device large-sized. <P>COPYRIGHT: (C)2004,JPO</p> |
