dc.description.abstract	a pulsed ytterbium-doped fiber laser is proposed and developed. a length of samarium-doped fiber was inserted into the laser cavity to induce passive q-switching. the laser oscillated in the continuous wave, q-switched mode-locked or q-switched regime depending on adjustment of the intracavity polarization controller and the pump power. q-switched pulses with a pulse energy of ~7.5 nj and duration of ~70 ns were obtained at a pump power of ~1500 mw, corresponding to a peak output power of ~106 mw at an average power of 2 mw. the low output power was attributed to the low coupling efficiency of pump radiation into the cavity and the high cavity losses. all results were obtained at room temperature.	en_us
