Multiple-beam, pulse-burst, passively Q-switched ceramic Nd:YAG laser under micro-lens array pumping
A passively Q-switched erbium-doped fiber laser (EDFL) was experimented on by employing graphene, single walled carbon nanotubes (SWCNT) and multi-walled nanotube (MWCNT) saturable absorbers (SA). The SA film obtained embedding the SWCNT MWCNT into polyvinyl alcohol (PVA). graphene prepared dipping a PVA thin solution while SAs were using casting method placed in ring cavity to produce stable p...
Passive Q-switching or mode-locking by placing a saturable absorber inside the laser cavity is one of the most effective and popular techniques for pulse generation. However, most of the current saturable absorbers cannot work well in the visible spectral region, which seriously impedes the progress of passively Q-switched/mode-locked visible pulsed fibre lasers. Here, we report a kind of visib...
