Features: This book summarizes the principles of laser polarization, with a focus on recent research achievements in orthogonal polarization lasers and their application areas. Chapter 1 provides an overview of the fundamental principles of lasers; Chapter 2 introduces the Zeeman dual-frequency laser and the four-frequency ring laser; Chapters 3 to 6 constitute the core of the book, offering new knowledge on laser experiments, phenomena, and applications that are not commonly found in existing specialized books and textbooks. These chapters systematically deepen and broaden the understanding of laser principles and technology. Chapters 3 and 4 discuss the principles by which various birefringence effects convert a single frequency of gas, Nd:YAG microchip, and semiconductor lasers into two orthogonal linearly polarized frequencies and control their frequency differences, presenting the structures of a series of orthogonal linearly polarized lasers. Chapter 5 describes the characteristics of orthogonal polarization lasers, such as frequency, power, polarization rotation, tuning, mode competition, and feedback. Chapter 6 elaborates on the principles and techniques for utilizing the orthogonal polarization properties of lasers to "evolve" the laser itself into a sensor, such as nanolaser rulers and wave plate phase delay measurement instruments. This book is suitable for teachers, scientists, technical managers, graduate students, and undergraduate students in universities and colleges who are engaged in laser teaching and scientific research both domestically and internationally.
