Abstract
We generated Q-switched and mode-locked pulses by making use of the saturable absorption characteristic of scandium oxide (Sc2O3) film, which was obtained by embedding Sc2O3 nanopowders into polyvinyl alcohol film. The Q-switched laser operated at center wavelength of 1560.5 nm with the maximum pulse energy of 65.6 nJ and 4.4% slope efficiency. With the addition of a 200 m extra single-mode fiber in the ring cavity, a self-starting mode-locked EDFL was implemented. The mode-locked pulses operated at a central wavelength of 1565.4 nm with a repetition rate of 1.0 MHz and a pulse duration of 3.50 ps. © 2020 Taylor & Francis.
