Course Description

A continuation of PHTN9120, this course provides an examination of specific laser systems and laser processes with the goals of providing practical experience and producing mathematical models of the laser. Power sources, excitation mechanisms, quantum processes, beam characteristics, and emission spectra for a selection of key commercial and research lasers including ion, CO2, excimer, YAG, ruby, and dye types will be examined. Specific features investigated include wavelength selection (for multi-line lasers), single frequency operation using intra-cavity etalons, pulse generation techniques (including Q-switching and modelocking), the operation of both acousto-optic and electro-optic modulators and switches, and non-linear optics (harmonic generation and OPO). Laser processes modeled include saturation of gain in an amplification medium, the modeling of lasers to optimize elements such as cavity optics, and the modeling of Q-switched lasers to predict output power, available energy, and key timing parameters. A laboratory component allows students to investigate lasing mechanisms and processes as well as the workings of practical lasers.
