摘　　要：研究了Nd:YVO_4激光晶体对808 nm附近光的吸收,定量给出了不同激活粒子浓度与其吸收808 nm光的关系.在测试晶体透过率基础上,通过计算,给出了Nd:YVO_4晶体808 nm波长光的吸收系数。实验得出了在确定浓度和长度的情况下,晶体对808 nm泵浦光吸收系数是一个不与泵浦源功率相关的确定值.计算了π和σ两偏振吸收,比较出它们之间的关系.The light absorption properties of Nd：YVO4 laser crystals at 808 nm were studied. The relationship between doped concentration and absorption coefficients was measured and calculated. Based on the transmission test, the absorption coefficients of Nd：YVO4 crystals were calculated. It is a determined value which is irrelevant to the pump power under the conditions of certain concentration and length of the crystal. The polarized 7r and a absorption were calculated and the relationship between them was compared
