Diode Laser Spectroscopy upper level physics experiments

This tunable diode laser spectroscopy experiment system is designed to investigate the principles of laser spectroscopy, atomic absorption, and high-resolution optical measurements using rubidium vapor. The modular system enables students to study diode laser characteristics, transmission spectroscopy, saturated absorption spectroscopy, interferometric frequency calibration, and advanced atomic physics phenomena such as hyperfine structure, Zeeman splitting, and Faraday rotation. The controller features independently configurable modules, allowing students to explore the effect of various experimental parameters through hands-on operation. Manufactured by Atico Export India.
