染料激光器的热透镜效应及三重态的消除方法

Thermal lens effect and triplet of dye laser and elliminating methods

介绍可调谐连续环状染料激光器的结构，给出克服热透镜效应和消除三重态的方法。

The tunable continuous ring dye laser is a useful laser source in nonlear optics,laser spectroscopy,photo chemistry and laser medicine.But the thermal lens effect and triplet are main problems to influence the applications.This paper introduces the cavity structure of the ring laser and the aberration compensation condition to provide the single mode operating.The experimental rasults show that proper COT added in EG solution can greatly improve the pumping efficiency.
