Graphene plasmonics provides a unique and robust platform for nonlinear optics. Defining features for graphene nonlinear plasmonics include the extreme optical confinement, giant Kerr nonlinear conductivity and configurable Fermi-level. With the recent theoretical examination of graphene's real and imaginary nonlinear conductivity by Cheng, Vermeulan and Sipe, we are able to study the full picture...
6-μJ, 6-μm pulses compressible to 1.5 optical cycles are generated in multistage OPA driven by 500-Hz Yb:CaF2-DPSSL. The system is favorable for verification of the predictions on λ-scaling of photoelectron wavepacket dynamics and atmospheric spectroscopy.
