|
摘要
基于长程气体吸收池技术,搭建了针对波长为1572 nm的单频激光的光谱纯度测量装置,理论分析了测量精度的影响因素,并推导出误差计算公式。结果表明,该装置可精确测量光谱纯度为90%～99.999%的激光输出。使用该装置对1572 nm种子注入光参量振荡器输出的单频纳秒脉冲进行测量,测得其光谱纯度为(99.996±0.0005)%,达到工业应用的要求。
A spectral purity measuring system based on long path absorption cell is built to measure the spectral purity of 1572 nm laser. The error calculation formula of this system is deduced and the factors influencing the measurement accuracy is theoretically analyzed. The results show that the accurately measured spectral purity range is 90%-99.999%. Based on this system, the spectral purity of a self-developed 1572 nm injection-seeded optical parameter oscillator is measured to be(99.996±0.0005)%, which fulfills the industrial application requirements.
