title: Ultrafast nonlinear sub-wavelength solid immersion spectroscopy at T = 8 K: an alternative to nonlinear scanning near-field optical microscopy.
abstract: Pump-probe measurements were performed with a subwavelength spatial resolution of 355 nm and a temporal resolution of 130 fs in a multiple quantum well sample at T= 8 K. A solid immersion lens was used to increase the spatial resolution to 0.41 lambda, demonstrating that the limit of conventional microscopy was surpassed.
