摘要

我们演示了一种高功率1 ghz克尔透镜锁模（KLM）镱：CYA激光器，输出149-fs脉冲，平均功率为11.1 W。相应的单脉冲能量和峰值功率分别为10.3 nJ和60.8 kW。锁模操作可以持续100分钟，功率波动的均方根（RMS）值仅为0.52%。据我们所知，这是迄今为止报道的从GHz飞秒锁模振荡器中获得的最高平均功率。

Kerr-lens mode-locked GHz-repetition-rate Yb:CYA laser with 11-W average power.

We demonstrate on a high-power 1-GHz Kerr-lens mode-locked (KLM) ytterbium (Yb):CYA laser delivering 149-fs pulses with an average power of 11.1 W. The corresponding single-pulse energy and peak power are 10.3 nJ and 60.8 kW, respectively. The mode-locking operation can be consistently sustained with root mean square (RMS) values of power fluctuations of only 0.52% for 100 min. To the best of our knowledge, this is the highest average power ever reported from a GHz femtosecond mode-locked oscillator.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
