Time-resolved second-harmonic generation was used to generate and detect coherent LO phonons in semiconductor heterojunctions. Three coherent LO/sub GaAs/, LO/sub GaAs-like/, and LO/sub AlAs-like/ phonons were launched by transiently screening the depletion field in the GaAs/Al/sub x/Ga/sub 1-x/ interfacial region.
