專利摘要(中)
提供了一種產生同調或類似雷射的輻射的介電光柵波導自由電子雷射裝置。電子束在具有內置光柵結構的介電波導旁邊傳播，通過光柵波導結構提供的布拉格共振、反向波共振或法布里-珀羅共振，在其中產生空間侷限的同調或類似雷射的輻射。介電光柵波導可以由線性光學材料或非線性光學材料或線性和非線性光學材料的組合製成，以實現多種功能，例如雷射生成、雷射波長轉換和雷射信號處理。由於雷射模態在介電波導內的增強，通過電子與表面模態場的耦合和聚束，在光柵上方也產生了同調或類似雷射的史密斯-珀塞爾輻射。

專利摘要(英)
A dielectric-grating waveguide free-electron laser device generating coherent or laser-like radiation is provided. An electron beam propagates next to a dielectric waveguide with a built-in grating structure to generate spatially confined coherent or laser-like radiation in the waveguide through the Bragg resonance, the backward-wave resonance, or the Fabry-Perot resonance provided by the grating-waveguide structure. The dielectric-grating waveguide can be made of linear optical materials or nonlinear optical materials or combination of linear and nonlinear optical materials to enable versatile functionalities, such as laser generation, laser-wavelength conversion, and laser signal processing. Owing to the build-up of the laser modes inside the dielectric waveguide, coherent or laser-like Smith-Purcell radiation is also generated above the grating via coupling and bunching of the electrons with the surface mode fields.
