Time-development of transient optical net gain spectra of InGaAs-InGaAsP MQW laser structure after ultrashort pulse excitation was measured. With theoretical simulation, the dynamics of carrier density, carrier temperature and bandgap renormalization and their influences on transient gain were investigated.
