Abstract:
YVO4 crystal has high laser output slope efficiency and damage threshold,good mechanical property and chemical stability.We have measured the absorption of Tm:YVO4 crystal.The anisotropy effect is taken account.The optical intensity parameters are fitted out.And the oscillator strength f,the radiative transition rate,the integral emission section Σ are calculated.In the wavelength range of 350—2500nm,the absorption of YVO4 crystal itself is rather small.However,Tm3+ ions in the YVO4 crystal have very strong luminescent ability. Especially,the 1D2→3F4 (about 454nm) blue transition has excellent oscillator strength (f=38×10-6) and integral emission section (Σ=33×10-18cm).It is quite benefit to achieve laser lasing in short-wavelength.In brief,the rare earth ion doped YVO4 crystal is a kind of wonderful laser material,which has great applications in future.
