摘要：

Efficient repetitive passive Q switching of a cladding-pumped Er-Yb fiber laser has been demonstrated by use of an external-cavity configuration containing a Co2+:ZnS crystal as a saturable absorber, Energies of as much as 60 muJ in pulses of durations as short as 3.5 ns (FWHM), corresponding to a peak power of .10 kW, have been generated, and the maximum slope efficiency with respect to the absorbed pump power was 13%. Using a bulk diffraction grating in the Littrow configuration to provide wavelength-selective Feedback, we tuned the passively Q-switched fiber laser over 31 nm from 1532 to 1563 nm. The prospects For further improvement in performance are discussed. (C) 2002 Optical Society of America.
