Doublet emission-based circularly polarized luminescence was successfully realized in luminescent π-radicals by applying three kinds of approaches, namely, induction by a longitudinal magnetic field, supramolecular chiral co-assembly, and doping into chiral liquid crystals.

In this paper, we study the electron acceleration by a circularly polarized electromagnetic wave propagating through plasma in the presence of a periodic and an axial guide magnetic field. A numerical calculation in MATLAB software was developed by employing the fourth-order Runge–Kutta method for studying the electron energy and electron trajectory in plasma medium. The equations governing the electron momentum and energy which describe electron acceleration by a circularly polarized laser pulse have been obtained. It is shown that by choosing an appropriate wiggler field frequency at short distances, the electron retains an adequate amount of energy. In addition, it is found that due to the simultaneous existence of the wiggler field and field of laser pulse and their combined effects, the electron in the direction of the laser pulse propagating, turns around and subsequently, the electron transverse momentum increases and as a result the electron escapes from the laser pulse near the laser pulse peak. Furthermore, it is seen that by increasing the laser intensity, the electron energy decreases and by decreasing to an appropriate value while employing a wiggler magnetic field, a higher peak of energy is gained.

The magneto-optic effect called mode-crossing is investigated. The crossings are produced with a polarization-stabilized two-mode 633-nm He-Ne laser. The beam from the laser interacts with a thermal neon gas absorber placed outside the laser. The absorber is in a tunable longitudinal magnetic field. The investigations are focused on the behavior of the crossing signals when the laser mode polarizations are varied. Both linearly and circularly polarized modes are used. The results are compared with conclusions that are drawn from couplings between the Zeeman sublevels in J = 1 to J = 0 systems. It is found that the number and the strength of mode-crossings can be controlled by selections of the mode polarizations.
