Adiabatic following in two-photon transition

Creators

Description

There has been much interest recently in coherent multiphoton transitions in many-level systems. The present work considers the effect of relaxation in the response of a three-level system to a smoothly varying, near-resonant, two-photon field. The relaxation-dependent contributions to the nonlinear refractive index are calculated. It is shown that the coherent interaction of two smoothly varying, near-resonant, two-photon pulses with a three-level system can be described by ''two-photon damped Bloch equations'' which are analogous to those for a one-photon transition in a two-level system except for the presence of a two-photon coupling and a frequency shift. 1 figure
