By: Soldatov, Anatoly NContributor(s): Vasilieva, Anna V | Томский государственный университет Факультет инновационных технологий Научные подразделения ФИТMaterial type: ArticleArticleSubject(s): лазеры на парах стронция | костные ткани | лазерное излучениеGenre/Form: статьи в журналах Online resources: Click here to access online In: AIP Conference Proceedings Vol. 1688. P. 060011-1-060011-5Abstract: A two-stage laser system consisting of a master oscillator and a power amplifier based on sources of selfcontained transitions in pairs SrI and SrII has been developed. The radiation spectrum contains 8 laser lines generating in the range of 1 – 6.45 μm, with a generation pulse length of 50 – 150 ns, and pulse energy of ~ 2.5 mJ. The divergence of the output beam was close to the diffraction and did not exceed 0.5 mrad. The control range of the laser pulse repetition rate varied from 10 to 15 000 Hz. The given laser system has allowed to perform ablation of bone tissue samples without visible thermal damage.
