Abstract

The development of a diode-pumped high peak power sub-100 fs mode-locked Yb:CALGO laser is presented. The laser delivered 1.3 W of output power with 81 fs pulses at a repetition rate of 26.9 MHz. The corresponding pulse energy was 48 nJ and the peak power was 596 kW. The cavity was extended by using a 1:1 imaging telescope. Mode locking was based on a semiconductor saturable absorber mirror and chirped mirrors were used to compensate for the positive dispersion in the cavity. To the best of our knowledge, this is one of the shortest pulse durations obtained from Yb:CALGO laser around this low repetition rate.

以 26.9 MHz 重复频率发出峰值功率低于 100 fs 脉冲的模式锁定 Yb:CALGO 激光器

本文介绍了一种二极管泵浦高峰值功率亚 100 fs 锁模 Yb:CALGO 激光器的研制过程。该激光器以 26.9 MHz 的重复频率发出 81 fs 脉冲，输出功率为 1.3 W。相应的脉冲能量为 48 nJ，峰值功率为 596 kW。腔体通过使用 1:1 成像望远镜进行扩展。模式锁定以半导体可饱和吸收镜为基础，并使用啁啾镜来补偿空腔中的正色散。据我们所知，这是 Yb:CALGO 激光器在如此低的重复率下获得的最短脉冲持续时间之一。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
