Watt-level Q-switched Nd:LuVO4 laser based on a graphene oxide saturable absorber

open access: yes, 2014
The demonstration is reported of a diode-pumped passively Q-switched Nd:LuVO4 laser at 1064 nm using a transmission-type graphene oxide as the saturable absorber. The graphene oxide saturable absorber with a modulation depth of 10% was fabricated using a

Dual-wavelength Q-switched thulium doped fiber laser with TiO2 film saturable absorber

open access: yes, 2018
We report a dual-wavelength Q-switched Thulium doped fiber laser based on a Titanium dioxide (TiO2) saturable absorber. The TiO2 was embedded in polyvinyl alcohol (PVA) film, which was then sandwiched in between two fiber ferrules in the cavity. By using

Q-switched and mode-locked diode-pumped Nd : YAG laser with an LT-GaAs

open access: yes, 2006
Simultaneous Q-switching and mode-locking (QML) is accomplished in a diode-pumped Nd:YAG laser using low-temperature GaAs (LT-GaAs) as the saturable absorber, which also acts as an output coupler at the same time.
