Optical and Physical Properties of Laser Glasses, in the consideration of laser glasses for practical applications. We refer particularly to impurity problems, thermal-shock resistance, durability, and intrinsic stress, all of which have been found to be important for consideration, in addition to the more fundamental properties previously discuss

Damage Effects in High-Peak-Power Nd : Glass Laser Systems,amage threshold to minimize the diameter. Although the general subject of optically induced damage has matured considerably in recent years, progress has been slow owing to the experimental and theoretical complexities. At the present time, workers in the field cannot even agree on the basic physica

Nonlinear Effects in High-Peak Power Nd: Glass Laser Systems,ll known to the experimentalist in this area. Although the basics of self-focusing theory (Sect.7.2–4) were known for some time previous to the advent of the construction of large Nd:glass laser systems, the major contribution here is the development of semi-phenomenological theories that enable the

Amplifiers for High-Peak Power Nd : Glass Laser Systems,t level. Optimization of the performance of such amplifiers leads to maximum system performance at minimum cost. In this chapter we investigate the general characteristics and present operating conditions for disk, active-mirror and rod amplifiers. It will be shown how it is possible to design an op
