The experimental setup employs an all-solid-state visible laser experimental platform using blue light to pump a Pr:YLF crystal. The core design utilizes 445 nm blue light pumping to achieve 640 nm red light output across the entire visible spectrum, enabling the full visual presentation of key laser generation elements such as the pump source, gain medium, resonant cavity, and output laser. The apparatus breaks through the limitations of the traditional "black box" design of laser experimental instruments, transforming abstract principles like laser stimulated emission, resonant cavity oscillation, and Gaussian beam transmission into physical processes that can be directly observed, manually adjusted, and quantitatively measured. It is also equipped with standardized optical alignment procedures and precision adjustment mechanisms, catering to both the verification of teaching principles and practical training in optical engineering.
