摘要：

The time resolved emission spectrum of the blue band of Ti:sapphire laser crystal has been investigated as a function of temperature (range 10-290 K) and UV (266 nm) laser excitation intensity. Two blue emission bands, centred at 420 nm and 460 nm, have been detected. The 420 nm band is attributed to Ti4+ centres whereas the 460 nm one is proposed to be due to Ti3+ ions. The evolution of the emission spectrum vs the UV excitation intensity has shown that the concentration of Ti4+ centres is increased under UV irradiation at the cost of the centres responsible for the 460 nm band.
