Lasers: An Introduction

Synopsis

The difference between the incoherent nature of normal light sources and the coherent light from a laser is explained. Animated diagrams show the essential parts of a laser and how the energy of stimulated atoms is released to give the laser beam. Gas and crystalline lasers are shown in action together with applications for medicine, industry and communications. Concludes with a demonstration of holography.
