Scalar Nanosecond Pulse Generation in a Nanotube Mode-Locked Environmentally Stable Fiber Laser
R. I. Woodward, E. J. R. Kelleher, D. Popa +5
We report an environmentally stable nanotube mode-locked fibre laser producing linearly-polarized, nanosecond pulses. A simple all-polarization-maintaining fibre ring cavity is use…
Few-cycle pulses from a graphene mode-locked all-fiber laser
D. Purdie, D. Popa, V. J. Wittwer +6
We combine a graphene mode-locked oscillator with an external compressor and achieve~29fs pulses with~52mW average power. This is a simple, low-cost, and robust setup, entirely fib…
Ultrafast and widely tuneable vertical-external-cavity surface-emitting laser, mode-locked by a graphene-integrated distributed Bragg reflector
C. A. Zaugg, Z. Sun, V. J. Wittwer +11
We report a versatile and cost-effective way of controlling the unsaturated loss, modulation depth and saturation fluence of graphene-based saturable absorbers (GSAs), by changing…
Wideband tunable, graphene-mode locked, ultrafast laser
Z. Sun, D. Popa, T. Hasan +5
We report a tunable ultrafast fiber laser mode-locked with a graphene saturable absorber. The linear dispersions of the Dirac electrons in graphene enable wideband tunability. We g…
