14.1 Introduction in lms are an integral part of any laser design. Coatings are used for reducing surface losses and ghosts (antireection), pulse trapping and beam combination (polarizers), and beam steering (mirrors). Unfortunately, near-infrared (NIR) lasers are typically uence limited by the coatings in the optical system. ese limitations can impact laser design by necessitating an increase in optic size to reduce the laser uence. Brewster’s angle windows have been incorporated into commercial NIR lasers to eliminate the need for uence-limiting antireection coatings. Commercial NIR lasers are also typically limited not only in uence, but the lifetime of reective coatings.
