Abstract

The determination of dephasing time T2 (or transverse relaxation time) associated with excited states of materials is of importance for its significant influences on light-matter interaction. The values of T2 are, however, very short generally in condensed matter, being often in a range of subpicosecond and femtosecond range. Although these extremely short values of T2 associated, in particular, with electronic excited states have hitherto been measured mostly by nonlinear spectroscopic methods in the frequency domain [1–5], it is also desirable to determine these values by observing the phenomena directly in the time domain to complement and compare with the results by the frequency-domain method. Conventional coherent transient methods are, however, hard to be applied at present for the relaxation study in this extreme time region due to the limitation of present laser performance.
