title

Experimental Implementation of Ultrafast Probe-Probe Correlation Spectroscopy

Abstract:

Probe-Probe Correlation Spectroscopy is a concept in spin noise spectroscopy, where the information about the sample system is extracted from the correlation between two probe pulses. It can be demonstrated, that such a system can be implemented and that the sample system of Samarium-Erbium-Orthoferrite (SmErFeO³) shows a response around the spatial and temporal overlap of the pulses stemming from the unique magnetic behaviour of the material. Furthermore, it can be shown, that this response depends on the temperature of the sample as well as on the optical power of the probe pulses. The basic working principle of this probe-probe correlation setup, as well as the first results from testing it with the orthoferrite sample, will be discussed in this talk.
