- 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 saturable absorber. Laser emission is obtained at three wavelength regions with central peak at around 1546, 1561, and 1862 nm. Multi-wavelength emission with separation of approximately 1 nm is obtained around the wavelength regions of 1546 and 1561 nm. Stable laser pulses are generated in the pump power range from 3.6 to 7.3 W.
