Abstract :
Summary form only. We pump the Ho/sup 3+/-doped fiber laser into the core using a high-power double-clad Yb/sup 3+/-doped fiber laser operating at 1.15 /spl mu/m. This wavelength corresponds to a sufficiently strong absorption band of Ho/sup 3+/ ions due to the laser transition. Also we use a Bragg grating with a resonance wavelength of 2 /spl mu/m as the input mirror of the laser.
