Abstract

The all-solid-state single-longitudinal-mode laser at 1064 nm has found a wide range of applications in laser spectroscopy, quantum physics, etc. By combining it with frequency locking techniques, a stable single-longitudinal-mode laser without mode-hopping can be achieved. Many frequency stabilization techniques typically require complex optoelectronic control systems. In this work, we present a continuous-wave single-longitudinal Nd:YVO₄ laser based on a ring resonator, employing a simple yet effective locking method. The laser frequency is locked to the edge of a particular absorption spectral line of the molecular iodine. Utilizing a feedback controller, we have achieved a frequency stability better than ±3.35 MHz over a duration of 7 h. To our knowledge, this represents one of the best long-term frequency locking results for this kind of single-longitudinal-mode Nd:YVO₄ laser. This stable single-longitudinal-mode laser will be a core component in the laser source of a differential absorption lidar system, which will be used in the future to monitor air pollutants and greenhouse gases.

基于分子碘吸收的1064 nm稳定全固态连续波单纵模Nd:YVO4激光器

1064nm全固态单纵模激光器在激光光谱学、量子物理等领域有着广泛的应用。将其与锁频技术相结合，可以实现无跳模的稳定单纵模激光器。许多频率稳定技术通常需要复杂的光电控制系统。在这项工作中，我们提出了一种基于环形谐振器的连续波单纵向Nd:YVO4激光器，采用了一种简单而有效的锁定方法。激光频率锁定在碘分子的特定吸收谱线的边缘。利用反馈控制器，我们在7小时的持续时间内实现了优于±3.35 MHz的频率稳定性。据我们所知，这代表了这种单纵模Nd:YVO4激光器的最佳长期频率锁定结果之一。这种稳定的单纵模激光器将成为差分吸收激光雷达系统激光源的核心部件，该系统将在未来用于监测空气污染物和温室气体。
