Witryna19 sie 2024 · In fiber lasers, NA is a unit-less number that is used to quantify the angles that the laser beam can have (incident to the fiber) as it travels through the fiber. It is the sine of the largest angle of an incident ray with respect to the fiber axis. The NA is typically calculated using the refractive indices of the core and cladding. WitrynaFundamentals of Fiber Optics Page - 4 - / Reinhard Jenny / 26.4.2000 An Introduction for Beginners NA = n sin (αMax) = √ n1 2 - n 2 2 (2) All angles, α ≤ αMax or β ≥ βMin, will be transmitted by the fiber with larger angles resulting as leaky modes (by refraction at the core/clad interface). WitrynaHere, ncore and ncladding are the refractive indices of core and cladding, respectively, and n0 is the refractive index of the medium around the fiber, which is close to 1 in the case of air. Figure 1: An incident light ray is first refracted and then undergoes total internal reflection at the core–cladding interface. election of rutherford b hayes date
