Course Description
Introduction to the basic principle of generation and properties of Laser, including semiclassical laser theory, line broadening mechanisms, optical resonators and steady-state and transient dynamics of laser oscillation. Laser modes, Quality factor (Q), Mode locking, Q-switching, Electro-optic effect: Kerr and Pockel effects, Magneto-optic effects: Faraday Effect and Acoustic-optic effect, Non-linear effects and Harmonic generation will be discussed. Examples of commonly used lasers, including Ruby laser, Gas laser – CO2 laser, He-Ne Laser, Semiconductor laser, Nd-YAG Laser. Quantum well laser, Dye laser and Polymer laser as well as laser application in holography, information technology, communication, printing, scanning, military, and medical research will be discussed.
