Ultrafast Spin Noise Spectroscopy With Variable Probing Wavelength
We present an ultrafast spin noise spectroscopy setup with wavelength tunability, enabling high-resolution detection of magnetic fluctuations. Our system can achieve ~10 −13 rad 2 /Hz sensitivity for spin dynamics with terahertz bandwidth. This capability opens new avenues for studying complex spin systems and phase transitions.
