  • Arrangement for the wavelength-selective internal intensity modulation and radiation pulse generation of high power CO.sub.2 lasers
    Patent number: 4845716
    Abstract: An arrangement for the wavelength-selective internal intensity modulation and radiation pulse generation of high power CO.sub.2 lasers, in a high-power CO.sub.2 laser is forced to operate in the resonator at a freely selectable but fixed wavelength by means of a frequency-selective element and highly angle-selective gas discharge tubes. The possibility of rapidly Q-switching is provided by a special interferometer arrangement of variable reflectivity, functioning as an uncoupling element. The arrangement may furthermore be used for the rapid stabilization of the laser power.
