摘要：
Ultra-broadband saturable Bragg reflectors consisting of a 7-period GaAs/AlxOy Bragg mirror and an InGaAs/InP quantum well were studied and used to start modelocking of 36 fs pulses near 1500 nm in a dispersion compensated Cr4+:YAG laser. The mirrors are comprised of high-index-contrast GaAs/AlxOy Bragg stacks grown as GaAs/AlAs and oxidized to create mirror areas as wide as 300 mum. They exhibit non-saturable losses smaller than 0.8% and a stopband from 1300 to 1800 nm, indicating the potential for the generation of shorter pulses. (C) 2002 Elsevier Science B.V.
