Laser Spectroscopy
2021-2022الفرقة الخامسة
Introduction to Lasers: Understanding the unique properties of lasers—coherence, monochromaticity, directionality, and intensity—and their historical development.
• Light-Matter Interaction: Exploring how photons interact with atoms and molecules, including absorption, emission, and scattering processes.
• Stimulated Emission and Population Inversion: Key concepts behind laser operation, including Einstein’s coefficients and energy level systems (2-level, 3-level, and 4-level models).
Laser Types: Solid-state, gas, dye, and semiconductor lasers, each suited for specific spectroscopy methods.
• Laser Cavity Design: Understanding modes, standing waves, and resonator configurations
