Abstract
We report the experimental investigation of an all-fiber multi-wavelength passively Q-switched Er/Yb laser with simultaneous gain-switched pulsed operation by using a thulium-doped fiber as a saturable absorber. Laser emission is obtained in three wavelength regions with central peaks at around 1546?nm, 1561?nm, and 1862?nm. Multi-wavelength emission with separation of approximately 1?nm is obtained around the wavelength regions of 1546?nm and 1561?nm. Stable laser pulses are generated in the pump power range from 3.6?W to 7.3?W.
