Optical properties of Ti:Al2O3 single crystal

Optical transmission and absorption spectra of Ti:Al2O3 single crystal have been determined in the region of UV-vis and infrared at room temperature. The main absorption peaks at 491 nm and 562 nm, the weak infrared absorption band at 650 nm and the strong UV absorption band below 300 nm are observe...
