摘要
本文采用半经典中布洛赫 (Bloch)方程方法研究近简并V -型三能级系统的自由感应衰减现象 。
A optical free induction decay is studied semiclassically in the V-type three-level system with two upper levels being almost degenerate in Bloch form. It is discussed that the systematic relaxation has effect on the signal field of the free-induction decay. The decay behavior has three contributions: a homogeneous part with transverse relaxation time and two inhomogeneous parts with different time constants that reflect the velocity bandwidth excited.
