Abstract

A model of radiation generation process in active tapered double-clad optical fibers based on rate equations in the adiabatic approximation is developed. The generation process in active tapered fibers with different geometric profiles and mirrors at both ends alloyed with ytterbium is numerically simulated. The advantages of tapered fibers over cylindrical fibers are demonstrated; these advantages include low power density, high output power, higher power slope efficiency, and smaller length required for achieving similar output power.
