A nanocomposite of titania-coated silica saturable absorber (TiO2–SiO2-SA) was fabricated via alkaline fusion and spin-coating. The TiO2–SiO2-SA possessed nonlinear saturable absorption and optical limiting effect with 30.35% modulation depth, 42.57 μJ/cm2 saturation fluence, and 0.0075 cm2/μJ two-p...
