近年來高亮度高發射頻率的X光雷射研究有突破性的進展，由於其具有短波長及飛秒級時寬的特性，使X光雷射成為各種前端科學研究與應用極具潛力的工具。本文將介紹筆者們研究的光場游離碰撞激發機制產生之X光雷射一系列的進展與成果，藉此也讓讀者瞭解X光雷射的一般架構、設計考量及輸出特性。

Many breakthroughs have been made in the development of high-brightness, high-repetition-rate, tabletop X-ray lasers recently. Because of their short wavelength and femtoseond-scale pulse duration, such X-ray lasers are of great potential for frontier research and application in various scientific fields. This article summarizes the accomplishments we have made on the development of optical-field-ionization collisional-excitation X-ray lasers, through which the readers can learn the basics for the general setup configuration, design considerations, and output characteristics of X-ray lasers.
