In the thirty years since the invention of the CO2 gas laser,
the major design issue has shifted from how to obtain the desired power
level to how to achieve reliable operation. At the same time, the
opening of many laser development facilities in the Former Soviet Union
has allowed their achievements and design approaches to be understood
and appreciated for the first time. Further, the industrial laser user
community has identified a number of emerging applications at higher
power levels (15-20 kW) than are attainable by most commercial
devices.
In High Power Lasers - Science and Engineering, the designers,
developers and users of high-power gas laser systems discuss design
approaches, methods of enhancing performance, new applications, and user
requirements.
