Abstract

We present a comprehensive study on the spatio temporal weak measurement of a chiral ultrafast optical pulse. We create a chiral vector wave packet by transmitting ultrashort laser pulse via a birefringent or magneto-optic medium. Employing time-resolved leakage radiation microscopy, we examine how the real and imaginary components of the weak value parameter ($\epsilon$) influence pulse propagation over time. Our technique allows us to detect and categorize the temporal polarization fluctuation in a $75$ fs pulse with an excellent repeatability. The achieved experimental results demonstrate a satisfactory consistency with the theoretical predictions.
