Absorption coefficients of an undoped YVO4 crystal

In this paper, the absorption coefficients α_o (for ordinary ray) and α_e (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 α_o measured by unpolarized light, and 0.00432 cm⁻¹ of α_o and 0.00420 cm⁻¹ of α_e 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.
