Fiber laser with simultaneous multi-wavelength er/yb passively q-switched and single-wavelength tm gain-switched operations Article uri icon

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. © 2019 Chinese Laser Press.
