Resonant and Time-Resolved Spin Noise Spectroscopy

Abstract

We demonstrate a method to extend the range of pulsed laser spin noise measurements to long spin lifetimes. We use an analog time-domain detection scheme with a bandwidth limited only by laser pulse duration. Our model uses statistics and Bloch-Torrey equations to extract the Lande g-factor, Faraday cross-section ${\sigma }_F$, and spin lifetime ${\tau }_S$, while accounting for finite detector response. Varying the magnetic field with a fixed probe-probe delay yields ${\tau }_S$ when it is longer than the laser repetition period. Varying the probe-probe delay with a fixed field produces a time-domain measurement of the correlation function.
