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…

Dynamic Spin Injection into Chemical Vapor Deposited Graphene
A. K. Patra, S. Singh, B. Barin +5
We demonstrate dynamic spin injection into chemical vapor deposition (CVD) grown graphene by spin pumping from permalloy (Py) layers. Ferromagnetic resonance measurements at room t…

2μm Solid-State Laser Mode-locked By Single-Layer Graphene
A. A. Lagatsky, Z. Sun, T. S. Kulmala +9
We report a 2μm ultrafast solid-state Tm:Lu2O3 laser, mode-locked by single-layer graphene, generating transform-limited~410fs pulses, with a spectral width~11.1nm at 2067nm. The m…
