Introduction to Photonics and Laser Physics with Applications

Lasers are ubiquitous-from deep space communication to lab on the chip to supermarket product scanning. Although they form an integral part of optics & photonics and extensively used in research areas of science and technology to create multibillion dollar industries, the progress in severely limited in the subcontinent due to lack of experimental training in this field. The need of the hour is to have a self-sufficient book containing laser-related concepts readily available to beginners. The book is written keeping undergraduate and graduate students in mind to possibly serve as a textbook. It is also aimed to provide fundamental reference material on ultrafast lasers and photonics for researchers in the field of optics and bioengineering.

Key Features:

• Proposed book deals with the basics of lasers.
• Contains a chapter dedicated to the required spectroscopy and the one for the line broadening mechanisms.
• Special emphasis on the phenomena related to modern ultrafast lasers, and their applications.
• Sufficient mathematics, instead of details have been given to be able to understand the topic by the reader.
• Basics of lasers, ultrafast lasers, Q-switching and modelocking, characterisation techniques of ultrafast pulses, four wave mixing, semiconductor and fibre lasers, high harmonic generation.

激光器無所不在-從深空通信到芯片實驗室到超市產品掃描。儘管它們是光學和光子學的重要組成部分，並且在科學和技術研究領域廣泛應用於創造數十億美元的產業，但在次大陸地區，由於缺乏這一領域的實驗培訓，進展受到嚴重限制。當務之急是擁有一本自給自足的書籍，其中包含與激光相關的概念，以便初學者能夠輕鬆獲取。本書的撰寫是針對本科和研究生學生，可能作為教科書使用。同時，它還旨在為光學和生物工程領域的研究人員提供超快激光和光子學的基礎參考資料。

主要特點：
- 本書介紹了激光的基礎知識。
- 包含一章專門介紹所需的光譜學和線寬擴展機制。
- 特別強調與現代超快激光相關的現象及其應用。
- 提供足夠的數學知識，以便讀者能夠理解主題，而不是深入細節。
- 包括激光的基礎知識、超快激光、Q開關和模鎖、超快脈衝的表徵技術、四波混頻、半導體和光纖激光、高次諧波產生。
