Abstract

Transient absorption experiments exhibit a gradual decrease in SE lifetimes with increasing excitation density, which seems to be fairly consistent with a model utilizing ASE. However, this behavior is no longer a direct evidence for SE or ASE. A direct way to clarify the disputes regarding the mechanism for SNEE is the time-resolved measurement of SNE under various excitation densities because its temporal profiles are expected to exhibit markedly different behaviors depending on its origins.
