Abstract

We present a novel design of wholly fiber-based mode scrambler. The device consists of two multimode fibers with halfball microlens finish, being at some distance and connected via liquid of a certain refractive index. The prototype was made using standard components. The laser output profile was proved to be stable and almost entirely independent of input conditions, i.e. varying positions and angles of input laser beam. Moreover, the mode scrambler of the new design shows a very good power throughput, reaching as much as 90% of the light power compared to a single multimode fiber.
