Nonlinear Effects in High-Peak Power Nd: Glass Laser Systems, self-focusing, discovered when high-power lasers first became available, presently limits the output of every laser system designed to operate at short (50–200 ps) pulse widths. Although the problem has yielded to a number of improvements in laser materials, most notably the development of low-nonl

The Design of High-Peak-Power Nd : Glass Laser Systems,Nd: glass laser systems. This final chapter will concentrate on applying what we have learned to the actual design of real laser systems operating in the short-pulse, high-peak-power regime when output is limited by nonlinear effects. Although it will become apparent that the subject matter precedin
