Abstract
High-beam-quality laser oscillation is obtained at two Sr+ and several Sr atom lines in the middle infrared spectral region with average output power of about 4 W in a sealed-off laser tube. Using the same laser tube construction and enhancing the active volume in bore and length, average output power of about 10 W is also achieved. Based on these laser tubes, master oscillator–powerful amplifier laser system, in which low-power high-beam-quality laser radiation from the oscillator is amplified to the required level of the energy laser parameters, is also developed and investigated.
