D-Optical Fiber and Cladding Pumped Optical Fiber Lasers
Abstract
This final report presents information in research relating to co-doping of potential cladding pumped optical fibers. The emphasis is on experiments conducted that permitted the comparison of a series of co-doped optical fiber preforms made using an aerosol deposition process developed at Brown University. A set-up was developed that uses ASE (Amplified Spontaneous Emission) as a vehicle by which the relative efficiencies of a series of co-doped Yb-Er optical fibers were examined. These fibers were compared with a fiber from Lucent Technologies. Work on the co-doping of optical fibers so obtain multiple lasing from a Tm-Er system was investigated. This laser permitted pumping at the convenient 980 wavelength to yield lasing at 1550 nm, at 1850 nm, or at both wavelengths. In addition, an attempt was made to extend a new technique that was developed for the tuning of fiber lasers to include the possibility of ultra-fast switching of fiber lasers over a wide wavelength regime. More work is needed in this area, particularly in waveguide design, in order to obtain the required wavelength selectivity.
