Pump-probe measurements were performed with a sub-wavelength 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 λ, demonstrating that the limit of conventional microscopy was surpassed.
