摘要
研究了Nd:YVO4 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:YVO4 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。
Abstract
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 π and σ absorption were calculated and the relationship between them was compared.
