II Self-Induced Transparency

摘要: Publisher Summary This chapter discusses the basic theory of self-induced transparency (SIT), using a plane wave incident optical pulse with uniform intensity. The absorber discussed in is simple two level absorber, for example, stop transition an Rb atom Maxwell's and Schroedinger's equations as addressed chapter. semiclassical treatment radiation field adequate SIT because contains many photons intensities beam areas used most experiments. threshold attained when becomes intense enough to cause state change coherently from ground excited back state. coherent process highly nonlinear compared linear absorption region where only very small admixtures upper are excited. also reviews experimental results. Several laser-absorber systems verify theoretical predictions. Primary emphasis on interpretation experiments problems possibilities.
