Phase Fluctuation and Damping in Two-Level Optical Resonance

摘要: The interaction of a monochromatic optical field with two-level atomic resonance is one the basic problems in quantum optics. For closed system, we can describe dynamics Bloch equations:1 $$\dot u = - \tilde \Delta v \frac{1}{{{{T'}_2}}}u$$ (1) $$\dot + \kappa \varepsilon w \frac{1}{{{{T'}_2}}}v$$ (2) $$\dot \frac{1}{{{T_1}}}\left( {w 1} \right).$$ (3)
