Measurement of Refractive Index and Absorption Coefficient

WitrynaThe refractive index of the ordinary ray is constant for any direction in the crystal, and of the extraordinary ray is variable and depends on the direction. In a uniaxial crystal for the direction parallel to the optical axis the refractive indices are equal. http://www2.optics.rochester.edu/workgroups/lukishova/QuantumOpticsLab/homepage/Lecture_Phase_Matching-Sept_27_2010.ppt So far, we have assumed that refraction is given by linear equations involving a spatially constant, scalar refractive index. These assumptions can break down in different ways, to be described in the following subsections. In some materials, the refractive index depends on the polarization and propagation direction of the light. This is called birefringence or optical anisotropy. how to describe a painting in writing

Witryna: 230 Light with linear polarization perpendicular to this axis will experience an ordinary refractive index n o while light polarized in parallel will experience an extraordinary refractive index n e.: 236 The birefringence of the material is the difference between these indices of refraction, Δn = n e − n o. WitrynaRefractive index n e n o Birefringent materials have different refractive indices for different polarizations: the “Ordinary” and “Extraordinary” refractive indices! Using this, we can satisfy the phase-matching condition. For example: Use the extraordinary polarization for and the ordinary for 2 : n
