Tight Focusing of Light Beams: Effect of Polarization, Phase, and Coherence
Tight Focusing Light Beams Effect of Polarization Phase Coherence
2013/7/3
The focusing theory of electromagnetic waves has been well developed. A scalar wave theory satisfactorily describes the focusing process for a small semi-aperture angle. However, the vectorial charact...
Non-linear magneto-optic and self polarization rotation by superposition of states
Non-linear magneto-optic self polarization rotation superposition of states Optics
2012/4/24
We report the observation of enhanced magneto-optic rotation as the coherent superposition of different hyperfine states is established in an atomic sample. The polarization rotation near the two phot...
