All-fiber Yb-doped laser mode-locked by nanotubes
(IEEE, 2013)Single-wall carbon nanotubes (SWNTs) and graphene have emerged as promising saturable absorbers (SAs), due to their broad operation bandwidth and fast recovery times [1-3]. However, Yb-doped fiber lasers mode-locked using ... -
Femtosecond pulse generation from a Ti3+: Sapphire laser near 800 nm with voltage reconfigurable graphene saturable absorbers
(OSA - The Optical Society, 2017)We experimentally show that a voltage-controlled graphene-gold supercapacitor saturable absorber (VCG-gold-SA) can be operated as a fast saturable absorber with adjustable linear absorption at wavelengths as low as 795 nm. ... -
Femtosecond pulse generation from an extended cavity Cr4+: Forsterite laser using graphene on YAG
(Optical Society of America, 2013)A room temperature, multipass-cavity, femtosecond Cr4+:forsterite laser was modelocked with a single-layer graphene saturable absorber on a YAG substrate. The resonator produced nearly transform-limited 92 fs pulses near ... -
Generation of Sub-20-fs Pulses From a Graphene Mode-Locked Laser
(OSA - The Optical Society, 2017)We demonstrate, what is to our knowledge, the shortest pulses directly generated to date from a solid-state laser, mode locked with a graphene saturable absorber (GSA). In the experiments, a low-threshold diode-pumped ... -
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 ... -
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 supercapacitor as a voltage controlled saturable absorber for femtosecond pulse generation
(OSA, 2014)For the first time to our knowledge, we employed a graphene supercapacitor as a voltage controlled saturable absorber at bias voltages of 0.5-1V to generate 84-fs pulses from a solid-state laser near 1255 nm. -
Graphene-gold supercapacitor as a voltage controlled saturable absorber for femtosecond pulse generation
(Optical Society of America, 2016-02)We report, for the first time to the best of our knowledge, use of a graphene-gold supercapacitor as a voltage controlled fast saturable absorber for femtosecond pulse generation. The unique design involving only one ... -
Graphene-gold supercapacitor as a voltage-controlled saturable absorber for femtosecond pulse generation
(OSA, 2015)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, ... -
Sub-80 fe dissipative soliton large-mode-area fiber laser
(2010)We report on high-energy ultrashort pulse generation from an all-normal-dispersion large-mode-area fiber laser by exploiting an efficient combination of nonlinear polarization evolution (NPE) and a semiconductor-based ...
