【摘要】 利用激光增益和放大自发辐射 (ASE)理论 ,对不同条件下的染料激光放大器的激光增益和ASE强度进行了数值计算。分析了当入射光强远小于和大于有效饱和光强时 ,激光增益和ASE强度与入射光相对强度的关系 ,讨论了在两种条件下ASE系数以及染料池端面反射系数对激光增益和ASE成分的影响。最后利用这些结果 ,对连续激光的多级染料放大系统的优化设计进行了讨论。更多还原

【Abstract】 Numerical calculations about the gain and ASE intensity of a dye laser amplifier are preformed in two cases: the input laser flux is far smaller or larger than effective saturation flux. The influences of ASE coefficient and reflective coefficient of dye cells on the gain and ASE intensity are discussed too. These results are used to discuss the optimizing design of a CW laser seeded multistage dye laser amplifier.更多还原
