In article number 2000441, Maciej Kowalczyk and co-workers developed a novel technique for simultaneous generation of two pulse trains from a single femtosecond laser. It is based on polarization-multiplexing in a birefringent gain medium and allowed to achieve the lowest relative noise ever demonstrated for any solid-state dual-comb laser. This simple technique can be utilized for free-running, but yet very precise spectroscopic measurements.

双梳状激光器：具有固有偏振复用的双梳状飞秒固态激光器（Laser Photonics Rev. 15(8)/2021）

在文章编号 2000441 中，Maciej Kowalczyk 及其同事开发了一种新技术，用于从单个飞秒激光器同时生成两个脉冲序列。它基于双折射增益介质中的偏振复用，并允许实现任何固态双梳状激光器所展示的最低相对噪声。这种简单的技术可用于自由运行但非常精确的光谱测量。
