Abstract
The exact solution of the transient hole-burning (THB) shape has been obtained for systems with a noncorrelated spectral exchange. The THB shapes have been studied for various values of pump Rabi frequency χ/2 π, time duration and pump–probe time separation. It is shown that the correlated line is dominant in the slow spectral diffusion limit, and it decays with 1/e time of the correlation time τ c; in the fast limit, the hole is mainly determined by the width of the equilibrium frequency distribution a. When χ→0, the linewidths are ∼3/ πτ c and 2 a/ π in the slow and fast limit, respectively. The model fails to explain the THB experiments in ruby. However, it is more suitable to describe the FID behaviors under the same experimental condition [V.S. Malinovsky, A. Szabo, Phys. Rev. A 55 (1997) 3826].
