Abstract
We report cw laser emission of a Pr, Yb-doped fiber in the red spectral region. Laser emission was achieved on the transition with a Ti:sapphire pump laser tuned to . A maximum output power of was obtained at an incident pump power of . The output power was increased to when pumping with was provided by two Ti:sapphire lasers. A photon avalanche process was found to contribute strongly to the population of the upper laser level.
