LARGE SCALE POLARIZATION MAINTAINING PHOTONIC CRYSTAL OPTICAL FIBER FOR HIGH PERFORMANCE COHERENT ANTI-STOKES RAMAN SCATTERING ENDOSCOPE, CAPABLE OF IMPLEMENTING EFFICIENT NONLINEAR COMBINATION OF A PUMP AND A STOKES BEAM

摘要

PURPOSE: A large scale polarization maintaining photonic crystal optical fiber for high performance coherent angti-stokes raman scattering endoscope is provided to prevent lowering of CARS signal generation efficiency due to a wave guide by restraining.;CONSTITUTION: The core(110) is composed of the silica. It is composed of the triangle form. The inside clad(120) is formed outside core. A plurality of air holes is formed on the inner side site into the hexagonal shape of the constant interval into the longitudinal direction of the optical fiber. The outside clad(130) is composed of the circular boundary shape covering the outside of the inside clad. The outside silica(140) protects the outside clad outside.;COPYRIGHT KIPO 2010
