Paper Abstract

We develop a theory of time-resolved pump–probe optical spectroscopy of intraband absorption of a probe pulse inside an anisotropic semiconductor nanorod. The absorption is preceded by the absorption of the pump pulse resonant to an interband transition. It is assumed that the resonantly exited states of the nanorod are interrelated via the relaxation induced by their interaction with a bath. We reveal the conditions for which the absorption of the probe’s pulse is governed by a simple formula regardless of the pulse’s shape. This formula is useful for the analysis of the experimental data containing information on the relaxation parameters of the nanorod’s electronic subsystem.
