摘要：A mode-locked solid state laser is disclosed for generating ultrashort opticalpulses from solid state material. The laser can comprise a solid state gain medium, atleast one mirror connected to the medium and a semiconductor multiple quantum wellsaturable (MQW) absorber in contact with the mirror, for mode-locking the solid stategain medium. The solid state medium can be composed of but is not limited to TitaniumSapphire, Cr:YAG, Cr:Fosterite, Nd:YAG, Nd:glass, color center lasers, semiconductordiode lasers, optically active fiber lasers, and the like. The absorber can include a

structure consisting of 70 Angstrom wells of GaAs and 100 Angstrom barriers of AlGaAs.The generated optical pulses can be used in a wide variety of applications such asdiagnostic testing, communications, computers, medicine, automotive applications andthe like.
