| Abstract: | The transmittance spectrum of Er~3+ ions in YVO_4 crystal has been measured. Its absorptive cross-sections are calculated on the basis of this spectrum. The phenomenological intensity parameters are obtained by the use formulas on integral absorptive cross-sections. The oscillator strength, the probability for radiative decay and the fluorescence emission lifetimes are calculated using iudd-Ofelt theory. In the light of above parameters, the optical properties of Er~3+ ions inYVO_4 on laser output and laser threshold energy(power) have been compared with those in YAG as host crystal. The advantages of YVO_4 as laser host crystal has been discussed. |
