摘要

报道了一种新型795 nm超窄外腔二极管激光器（ecdl）。采用法拉第反常色散滤光片（FADOF）构建外腔。二极管激光器的光谱严格锁定在d1线（~794.98 nm），频宽（FWHM）从自由运行时的2.5 nm缩小到0.005 nm (2.5 GHz)，侧模抑制比为26 dB。二极管激光器的最终输出功率为58 W，外腔效率为60%。具有这种光谱特性和输出功率的二极管激光器在生物医学磁共振成像、自由空间光通信、自旋交换光泵浦、基础自旋物理研究等领域具有广泛的应用前景。

An Ultra-Narrow High-Power Faraday Laser Locked to the D1 Line of Rubidium

We reported a new kind of 795 nm ultra-narrow external cavity diode lasers (ECDLs). A Faraday anomalous dispersion optical filter (FADOF) was used to construct the external cavity. The spectrum of the diode laser was strictly locked to the D1-line (~794.98 nm), and the bandwidth (FWHM) was narrowed from 2.5 nm in the free-running case to 0.005 nm (2.5 GHz) with a side mode suppression ratio of 26 dB. The final output power of the diode laser was 58 W, with an external cavity efficiency of 60%. The diode laser with such spectrum characteristics and output power could have wide applications, including biomedical magnetic resonance imaging (MRI), free-space optical communications, spin-exchange optical pumping, fundamental spin physics research, etc.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
