摘要：

In this paper we introduce novel time-resolved photoluminescence spectroscopy called femtosecond two pulses induced stimulated emission spectroscopy, in which the generated nonlinear photoluminescence signal was used to identify the ultrafast dynamics of stimulated emission process in the semiconductor material. By employing two collinear fundamental femtosecond laser beams, we systematically investigated time-resolved multiphoton-induced amplified spontaneous emission in ZnO single crystal. Our results demonstrate the feasibility of this technique with the advantage of easy setup and high time resolution.
