Graphene supercapacitor as a voltage controlled saturable absorber for femtosecond pulse generation
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
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, ...
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 ...
