Light sensor Physics Lab Experiment Setup

This experiment system is designed for studying semiconductor-pumped solid-state laser technology and optical frequency doubling principles. Using an 808 nm semiconductor-pumped Nd:YVO₄ laser as the research platform, the system enables students to learn laser alignment and debugging techniques, observe frequency doubling phenomena, and perform measurements of threshold characteristics, phase matching, and laser output parameters. The system combines theoretical learning with practical experimentation, providing a comprehensive platform for advanced laser and nonlinear optics studies.
