Hanle Effect in the Metastable State of 4He Atoms with Arbitrarily Polarized Light

He Wang, Teng Wu, Wei Xiao +4 more

We present theoretical study of the Hanle effect in the metastable state of4He atoms with arbitrarily polarized light. The orientation and alignment components of the atomic polarization produce resonance signals with different line shapes. The amplitudes and line shapes of Hanle resonance signals have significant dependence on the light polarization. Our results can be used as an efficient method to determine the polarization component of the laser light, which is crucial for atomic physics experiments employing resonant light-atom interactions.

The Relevance of Hanle Effect on Na and Fe Lidars

C. Y. She

A laser resonant scattering process involves two steps, excitation and emission. That emission occurs spontaneously is well accepted. That the atoms involved in the emission are excited coherently by a laser beam leading to a non-isotropic angular distribution of emission (an antenna pattern) is not well known. The difference between coherent and incoherent excitation leads to the Hanle effect. In this paper, I discuss the physics of Hanle effect, and its influences on the backward scattering intensity of Na, K, and Fe atomic transitions and the associated Na and Fe resonant fluorescence lidar systems.

INTRODUCTORY PAPER ON HANLE EFFECT, LEVEL CROSSING AND DOUBLE RESONANCE EXPERIMENTS

Hans Bucka

The author reviews experimental techniques which use the properties of the scattering of light by free atoms in the neighborhood of a resonant frequency for investigation of excited atomic energy levels : - Hanle effect and its recent developments : (Hanle effect in an electrostatic field, molecular Hanle effect, Hanle effect of stepwise excited levels, sensitized fluorescence Hanle effect). - Double resonance experiments and its variations (« light beats »), excitation with modulated light...). - Level crossings and anticrossings (including of the study Stark effect by level crossings).
