Abstract

The invention relates to a Ti (titanium)-doped gallium oxide crystal, as well as a preparation method and application thereof. The molecular formula of the crystal is beta-(Ga1-xTix)2O3, x being lager than 0.0001 and less than 0.1. The crystal beta-(Ga1-xTix)2O3 is grown by adopting an edge-defined film-fed crystal growth method. Ti is adopted as an active ion, a fluorescence spectrum is positioned in a visible and near infrared bands, an emission spectrum is relatively broad, and the crystal is suitable for output of ultrafast laser of the band and output of tunable laser of a broadband. Compared with the prior art, the Ti-doped gallium oxide crystal has the advantages of high heat conductivity, low lattice distortion after doping of the Ti ion and capability of serving as an ultrafast laser and tunable laser gain medium.
