Design of lasers relevant to their application,n features. Because of space limitations, and because most applications are remote from the field of the laser itself, we will not attempt to discuss the applications themselves. Rather we will describe the design and engineering aspects of the lasers employed in different fields. Important features and critical parameters will be highlighted.
