This experiment enables students to install and tune the laser by themselves, master the basic principle, basic structure, main parameters, output characteristics and adjustment method of the laser, and make students have a comprehensive understanding of the principle and laser technology of the laser by observing the phenomena of Q-switching, mode selection and frequency doubling. It is mainly used in physics teaching and research in Colleges and universities.
