312 PHYS 7 4 3 - 3 412PhysLaser and its

applications

Brief description

This course is designed to provide students with the fundamentals of laser

oscillation, its properties and applications. It describes the interaction of

photon with matter and covers the essential laser requirements, laser gain

media, laser oscillations inside various resonators, and their stabilityconditions. It also discusses the laser beam characteristics, transformation,

and mode structure. It enables students to explore some of the laser types

and the related aspects of various technological applications that employ

lasers and beam optics.

ea-nesses and Su""estions

$ The time allowed to cover the necessary fundamentals of lasers and

their related theories as well as application seems not sufficient to give

a full picture especially in applications

$ 0ave optics transformation requires that student have some prior

!nowledge in 1/ ray tracing but that is not covered in previouscourses
