Introduction,. So even if readers find themselves offered more than one path to follow, they should have confidence that each of these paths can lead to a valid result. Indeed, this kind of duplication was considered an instructive feature of the earlier Laser Workshop Courses on which this book is based.

Laser beam geometry and its applications,uld still be 1 mm wide thousands of miles away’. In fact, nothing could be further from the truth. A laser beam has a finite size which changes as it propagates, and a proper understanding of these changes is needed in order to use such a beam successfully in alignment applications (Williams 1983).
