Tunable, efficient, ultrafast broadband nonlinear optical properties of TiO2–loaded complex phosphate glasses

•Nonlinear optical properties of TiO2 incorporated multicomponent phosphate glasses has been investigated.•The two-photon and three‒photon absorption nonlinearities respectively in 400‒800 nm and 1000‒1200 nm spectral irradiations were realized.•Structure‒nonlinear optical property correlations have been underlined.•The outcomes of the study acknowledge a new approach for conceiving highly nonlinear optical phosphate glasses through the polymerization of (PO4)3−groups.
