Ultrafast near infrared photoinduced absorption in a multiferroic single crystal of bismuth ferrite
Eiichi Matsubara, Takeshi Mochizuki, Masaya Nagai +2
We studied the ultrafast third-order optical nonlinearity in a single crystal of multiferroic bismuth ferrite (BiFeO3) in the near-infrared range of 0.5-1.0 eV, where the material…

Dimensionality dependence of optical nonlinearity and relaxation dynamics in cuprates
M. Ashida, Y. Taguchi, Y. Tokura +4
Femtosecond pump-probe measurements find pronounced dimensionality dependence of the optical nonlinearity in cuprates. Although the coherent two-photon absorption (TPA) and linear…
