Скачать или смотреть Perfectly coupled - Fiber Coupling using the Laser Beam Coupler series 60SMS

Long-term stable fiber-coupling requires sub-micron precision and pointing stability. This is especially true when a polarization-maintaining single mode fiber is to be permanently attached to a free beam laser. Tests of the popular single-mode coupler series 60SMS have shown that it is possible to achieve outstanding long-term stability over a wide temperature range while having a sensitive adjustment procedure.
We will give a short overview about the products and technologies at Schäfter+Kirchhoff and then we will present the technical features of the laser beam coupler series 60SMS and show and explain all the degrees of freedom used in the coupler to achieve high coupling efficiencies. We will then show stability measurements that prove the long-term stability. Following an explanation on the different lens types that can be used in the coupler we will explain how accurate measurements of the effective fiber numerical NAe2 provide the basis for choosing the most appropriate coupling and collimating optics. Afterwards we will introduce the Product Configurator for fiber couplers and collimators on www.sukhamburg.com that makes the process of choosing the most appropriate coupler for an application quick and easy.
