Abstract
We investigate and report the optical and laser characteristics of a
ytterbium-doped transverse Anderson localizing optical fiber to
develop a fundamental understanding of the light propagation,
generation, and amplification processes in this novel fiber.
Ultimately, the goal based on the measurements and calculations
conducted herein is to design and build a random fiber laser with a
highly directional beam. The measurements are based on certain
observations of the laser pump propagation and amplified spontaneous
emission generation in this fiber. Judicious approximations are used
in the propagation equations to obtain the relevant desired parameters
in simple theoretical fits to experimental observations, without
resorting to speculations based on the intended construction from the
fiber preform.
