Paper Abstract

The work presents results of the measurement of spatial and polarization far-field characteristics of the output radiation from the double-clad fiber. The beam width is found to depend on the input conditions. Polarization characteristics of the beam show existence of spatially-incoherent fields in the fiber which cause depolarization of the total output field. Theoretical interpretation of the effects is done in the framework of the modal approach. By means of numerical simulations it is shown that far-field output beam width, as well as its degree of polarization, depends on the input Gaussian beam spatial parameters due to interference between core mode and cladding modes of the fiber.
