Abstract

PURPOSE: Coupling efficiency is enhanced by once reflecting the radiation end of a laser of more than the critical incident angle of a fiber with the internal mirror which is reductively tapered from fiber coupling face toward laser coupling face and letting it enter at the incident angle smaller than the critical angle.
