  • Patent number: 6490299
    Abstract: Embodiments of methods and an apparatus for generating a specific laser radiation for production of high quality laser-induced damage images are disclosed. One or more embodiments of the invention comprise a method and system for generating the specific laser radiation by serial combination of both generation regimes: a Q-switched mode and a free-running mode. According to the invention the combination of both regimes is produced during a single flash of a pulsed pumping source by successive switching a loss level in a resonant cavity. Desirable ratio of a Q-switched pulse energy and a free-running mode pulse energy is achieved by adjusting the time delay of Q-switching and the threshold level in the resonant cavity. A Q-switched pulse creates laser-induced breakdown and a free-running pulse maintains plasma of the breakdown as long as it is necessary to create a damage of a desirable size.
