Oscillations of photocurrent signals upon photoionization of polarized Ar and Xe atoms in magnetic fields

Abstract

Ionization of polarized states of Ar and Xe atoms by femtosecond probe pulse in a supersonic beam in the presence of magnetic field was studied theoretically and experimentally. The revealed oscillation structure in the photoionization signals occurs due to the Larmor precession of exited atomic states in a magnetic field. We derived analytical formulas for the photoelectron current and explained the detected oscillations in terms of photon and atomic polarization moments. Our results indicate the possibility of implementing Doppler-free spectroscopy involving bound-free transitions.

Between 2009 and 2015 I studied at the Faculty of Physics of St. Petersburg State University and received my Master’s degree in "Physical optics and lasers". And now I continue my education, doing my PhD research in Physics. The topic of my thesis is quantum beats research of nearby atomic states in inert gases under multiphoton femtosecond optical pumping. My supervisor is a PhD in physics and mathematics A.A. Pastor. He occupies the associate professor’s position at the Department of Optics.
