In this course, we will learn the underlying physics of Lasers and laser systems by combining the knowledge of gain media together with the aspects of design, configuration and operation of lasers. By the end of the course, students will understand basic light matter interaction,
characteristics of atomic transitions and line broadening mechanisms, the necessary and
sufficient conditions for laser operation, basic laser beam characteristics and its relation to
cavity parameters, steady-state and transient operations, threshold requirements, different
types of lasers and laser applications.
