Comment on "Saturation of the All-Optical Kerr Effect"
J. K. Wahlstrand, H. M. Milchberg
Brée, Demircan, and Steinmeyer [Phys. Rev. Lett. 106, 183902 (2011)] recently calculated higher-order Kerr effect (HOKE) coefficients using the nonlinear Kramers-Kronig relations.…
Dual-gated bilayer graphene hot electron bolometer
J. Yan, M. -H. Kim, J. A. Elle +5
Detection of infrared light is central to diverse applications in security, medicine, astronomy, materials science, and biology. Often different materials and detection mechanisms…
Effect of a plasma grating on pump-probe experiments near the ionization threshold in gases
J. K. Wahlstrand, H. M. Milchberg
Calculations are performed of the phase shift caused by the spatial modulation in the plasma density due to interference between a strong pump pulse and a weak probe pulse. It is s…
Optical nonlinearity in Ar and N near the ionization threshold
J. K. Wahlstrand, Y. -H. Cheng, Y. -H. Chen +1
We directly measure the nonlinear optical response in argon and nitrogen in a thin gas target to laser intensities near the ionization threshold. No instantaneous negative nonlinea…
