Iodine-stabilized single-longitudinal-mode laser enhances atmospheric sensing and environmental monitoring

A research team led by Prof. Zhang Tianshu at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a compact all-solid-state continuous-wave (CW) single-longitudinal-mode (SLM) laser with high frequency stability using iodine-based frequency locking, advancing its application in atmospheric remote sensing and environmental monitoring. The study is published in Optics and Laser Technology.
