Paper Abstract

The Nd:YAG laser is finding more uses every day, in both military and commercial applications. The laser is now treated more as a component than a separate system, and this trend has led to a whole new set of engineering challenges. The layout of an integrated system, optical design considerations, damage problems, alignment needs and techniques, and integrated system testing will all be discussed in this paper. System layout must take into account all interfaces, especially from a maintainability viewpoint, and often includes the use of a common optical path for several subsystems. Optical design problems include a spectrum which is much wider than normal, restrictions on intermediate foci, and a new meaning to the term "multiple configurations". Careful attention must be paid to laser-induced damage of both people and hardware. Narcissus is the biggest nuisance, and the use of cemented surfaces is severely restricted. Elements must sometimes be added to avoid problems. Alignment, both internally (between subsystems), and externally (boresight) must be a major design factor. Finally, testing requirements often influence system layout. Some examples of design tricks and gadgets are included, based on both a military rangefinder and a com-mercial welder system.
