Graphene mode-locked femtosecond Cr: LiSAF laser
(Optical Society of America (OSA), 2015)
We report the first demonstration of femtosecond pulse generation from a Cr:LiSAF laser mode-locked with a monolayer graphene saturable absorber. Nearly transform-limited 72-fs pulses were generated at 850 nm with only two ...
Graphene-gold supercapacitor as a voltage-controlled saturable absorber for femtosecond pulse generation
We report, for the first time to our knowledge, a voltage-controlled graphene-gold supercapacitor saturable absorber, as a modulator with adjustable insertion loss for low-gain mode-locked lasers. Nearly transform-limited, ...
Graphene mode-locked Cr:LiSAF laser at 850 nm
(OSA - The Optical Society, 2015)
We report, for the first time to our knowledge, a mode-locked femtosecond Cr:LiSAF laser initiated with a high-quality monolayer graphene saturable absorber (GSA), synthesized by chemical-vapor deposition. The tight-focusing ...
