温度对强激光泵浦下激光染料荧光性能的影响

对三种在染料激光器中常用的激光染料(若丹明6G、硫化若丹明B、若丹明101)的乙醇溶液在强激光泵浦下的荧光性能进行了实验研究.测量了荧光强度在不同溶液浓度、不同温度下的变化规律.发现了温度对染料的最佳浓度值有一定影响:随着温度的降低,硫化若丹明B和若丹明101的最佳浓度值减小,而若丹明6G的最佳浓度值不随溶液温度变化.

Influence of Temperature on the Fluorescent Characteristic of Dye Laser Materials Pumped by High power Laser

Fluorescent characteristic of dye laser materials including Rhodamine 6G,vulcanized Rhodamine B and Rhodamine 101,pumped by high-power laser was experimentally studied.Experiments were taken under various conditions such as: different solution density,different temperature etc.Experiment results show that for each kind of the materials,the optimized solution density corresponding to the largest fluorescent intensity,is influenced by the temperature of the dye solution to some extent.For vulcanized Rhodamine B and Rhodamine 101 the value of the optimized solution decreases as the temperature decreases,while for Rhodamine 6G the value does not change as the temperature changes.Theoretic analysis of these phenomenon was done in the end of the article.
