摘要

本文给出了基于修正Bloch方程的非矩形激光脉冲原子共振能级居群动力学的数值计算结果。引用的方程描述了两能级原子系综和共振辐射之间的相互作用,并说明了原子偶极子-偶极子相互作用。发现ch-1激光脉冲与矩形脉冲相比,在绝热慢变作用场强下原子共振能级居群的临时动力学中具有更强的表现内部光学双稳效应的可能性

Numerical Modelling a Populations Differences Dynamics of the Resonant Levels of Atoms in a Nonrectangular Form Laser Pulse: Optical Bistability Effect
The results of numeric calculation of population kinetics of resonant levels for atoms in the non-rectangular form laser pulse on the basis of the modified Bloch equations are presented. Cited equations describe an interaction between two-level atoms ensemble and resonant radiation with an account of the atomic dipole-dipole interaction. It has been found for a case of ch-1 laser pulse a strengthen possibility of manifestation of the internal optical bistability effect special features in the temporary dynamics of populations for the atomic resonant levels under adiabatic slow changing the acting field intensity in comparison with a case of the rectangular form pulses
