Speeding up a single quantum dot pump-probe experiment — •Gerhard Johannes Schäfer, Christian Dicken, and Markus Lippitz — Experimental Physics III, University of Bayreuth, Germany

We recently showed [1], that it is possible to measure transient reflection on single semiconductor quantum dots in the far field.

Here we show how to improve those measurements. We decrease the integration time by using a high repetition rate laser (1 GHz instead of 76 MHz). At the same time, we also increase the spectral rate to 120 kHz.
