Z-scan measurement of the nonlinear refractive index of graphene [PDF]
Optics Letters, 2012 Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. Here, we unambiguously distinguish these two nonlinear optical effects and identify both real and imaginary parts of the complex nonlinear refractive index of graphene.

Dual THz Wave and X-ray Generation from a Water Film under Femtosecond Laser Excitation
Nanomaterials, 2018 Simultaneous emission of the THz wave and hard X-ray from thin water free-flow was induced by the irradiation of tightly-focused femtosecond laser pulses (35 fs, 800 nm, 500 Hz) in air. Intensity measurements of the THz wave and X-ray were carried out at
