All-fiber laser with simultaneous Tm3 passive Q-switched and Ho3 gain-switched operation Article uri icon

abstract

  • We experimentally demonstrate simultaneous Tm3 passive Q-switched (PQS) and Ho3 gain-switched laser operations at 1888.8 and 2021.2 nm, respectively, in a single-cavity all-fiber laser. The PQS operation of the Tm3 laser is based on the use of a high-concentration holmium-doped fiber as a fiber saturable absorber. Then the Tm3 laser emission is used as a pulsed pump source to achieve Ho3 gain-switched pulses. A high birefringence fiber optical loop mirror used as a spectral filter allows the tuning of both Tm3 and Ho3 laser emissions. © 2018 Optical Society of America
