摘要
本文就多纵模Ar^+激光时间相干性(即相干长度)与输出功率的关系进行了实验观测,得到了相干长度与输出功率关系近似为双曲线函数的实验结果,并根据简单的Smith模型,对多纵模激光的时间相干性与输出功率进行了理论分析与数值计算.研究结果表明,理论与实验结果基本吻合.
The relationship between the temporal coherence (i.e. the coherence length) and the output power of a multi-longitudinal mode Ar+ laser is studied. The experimental measurements show that the coherence length behaves a hyperbola as a function of the output power. A simple model of multimode equal amplitude power spectrum is employed in the theoretical analysis. Good agreement between theory and experiment is obtained, It is shown that for a multi-longitudinal mode Ar+ laser, the product of the coherence length and the output power is almost a constant.
