"Laser Principles and Techniques" is a professional basic course for optical information science and technology, and is listed as a core compulsory course in the teaching and training program. Laser principle and technology is an important branch of optics. It plays an important role in modern information science, especially optoelectronic information science. It has strong theoretical, cutting-edge and exploratory nature. The generation of laser has an epoch-making significance, and it has broad application prospects in both scientific development and technical application.

The goal of "Laser Principles and Techniques" is to enable students to master the basic principles of laser generation and formation, to develop students' theoretical thinking ability, and to train students' ability to analyze and solve practical problems. After completing this course, students will be able to master the basic principles and theories of lasers in a comprehensive way, and learn basic laser technology, which will lay the foundation for the follow-up courses in optoelectronic devices, photoelectric detection, optical fiber communication, etc., and also become the photoelectric field for students in the future. Senior professionals in management, development and design lay the necessary professional theoretical foundations. The course "Laser Principles and Techniques" is a junior in optical information science and technology. Before studying this course, you must first complete Advanced Mathematics, Mathematical Methods, University Physics, Electromagnetic Theory, and Some basic courses such as Quantum Mechanics and Statistical Physics, after studying this course, can lay the foundation for the follow-up courses of the major: "photoelectron detection technology", "optical communication technology" and "optical information comprehensive experiment".
