雷射原理與超快光學

This course is an introductory course in lasers and ultrafast optics. The main purpose is for students to obtain a solid understanding of laser basic principles, be familiar with the operation of most common laser types and broaden their horizons on frontier laser technology. --- 雷射技術展現了人類在科技與工程領域中操控光子行為的終極能力,其發展歷程不僅體現了科學從古典理論向量子電動力學統一框架的演進,也為我們勾勒出近代物理發展的全貌。 雷射的發明為現代科技帶來深遠影響,從精準定義時間(秒)、產生超短脈衝、應用於生醫雷射技術、推動半導體高解析製程,到成為量子電腦的關鍵平台,雷射的操控在各領域中均扮演著不可或缺的重要角色。 Laser technology demonstrates humanity's ultimate capability to manipulate photon behavior in science and engineering. Its development not only reflects the transition of scientific understanding from classical theories to the unified framework of quantum electrodynamics but also provides a comprehensive view of the evolution of modern physics. The invention of lasers has profoundly impacted modern technology, enabling precise time definition (seconds), the generation of ultrashort pulses, advancements in biomedical laser applications, high-resolution semiconductor manufacturing processes, and serving as a critical platform for quantum computing. The control of lasers plays an indispensable role in these diverse fields.

It would be helpful with a background in modern physics, electromagnetism, and optics.
