Category：Specialized（optional course）
Prerequisites：Optical electronics
Audience：Undergraduate students
Teaching manner：Classroom lecturing + experiments
Course objectives and basic requirements:
This course is aimed at laser technique related knowledge and training. It helps students to improve the specialized fundamental theories. The students are required to command the basic approaches and the main methods and principles related to laser techniques and also a good understanding of the laser modulation, Q switch, ultra short-pulse laser, laser amplification, mode selection and frequency stabilization.
Course introduction:
This course mainly includes the laser modulation, Q switch, ultra short-pulse laser, laser amplification, mode selection and frequency stabilization. It will begin from the laser modulation and introduce the basic working principle of different types of Q-switching techniques in more detail. It will introduce the current available approaches of realizing ultra-short pulse. It will also discuss the basic principle of laser amplification, as well as the mode selection and frequency stabilization.
