Abstract
Changes in the transmission of quasi-zero-dimensional CdSe microcrystals (quantum dots) induced by ultrashort laser pulses were investigated with picosecond time resolution. The transitions between the energy levels of electrons and holes spatially confined within microcrystals were observed as bleaching bands in nonlinear transmission spectra. Gain registered at the transitions between the lowest levels of size quantization in microcrystals allowed to achieve the regime of laser generation in Fabry-Perot resonator made of glass containing semiconductor microcrystals.
