A study of an innovative waveguide structure including hollow optical fiber HOF with a central hole and rare earth doped ring core is investigated. The HOGF serves as a novel fiber laser and amplifier gain medium. The central air hole and glass ring core gives an access to chromatic dispersion control, while the rare earth doped ring and its adiabatic taper endows a new degree of freedom to design clad pumped fiber laser gain medium that has not been available in the prior arts. The project encompasses the design of the HOF and its fabrication, then active device implementation and characterization. Optimal design parameters are obtained for applications for LIDAR systems and other optical applications.
