    Abstract

    In this paper, semiconductor saturable absorber mirror designed for the near-IR spectra and based on InGaAs quantum dots was investigated. Absorption saturation, absorption femtosecond recovery kinetics measured at various close to resonance quantum energies revealed the wavelength ~ 1050 nm as best performing absorption bleaching (highest value of 2 % for reflectivity change) for this sample. Nonlinear absorption, carrier thermalization appeared to govern carrier generation, their dynamics in the quantum dots.
