Absorption coefficients of an undoped YVO4 crystal

In this paper, the absorption coefficients αo (for ordinary ray) and αe (for extraordinary ray) of an undoped YVO4 crystal were calculated by measuring the transmissivities and refractive indices. The mean values 0.00549 cm−1 of αo measured by unpolarized light, and 0.00432 cm−1 of αo and 0.00420 cm−1 of αe measured by linear polarized light were reported, respectively. The corresponding absorption curves were given. The discussions about the errors were made. This work is available to evaluate quantificationally the quality of undoped YVO4 crystal and provides the significant data of absorption coefficient for its applications.
