Flexible optical device for the transmission of light and use of the device

Abstract

Abstract Flexible, optical components made from transparent quartz and having a core (5) and a cladding (6) surrounding the latter are used for the transmission of ultraviolet light at high power densities, which components have in front of a flexible, cylindrical region (2) a tapering region (3) whose cross-sectional surface continuously decreases when seen in the irradiation direction. In order to obtain such a component, which with regard to material damage caused by the ultraviolet radiation to be transmitted has increased destruction thresholds, and whose geometrical configuration is optimised with regard to the excitation conditions for the light to be transmitted and with regard to obtaining the mechanical and optical properties during use as stipulated, in the core glass a content of hydroxyl ions in the range from 50 ppm to 1200 ppm is specified, and a content of hydrogen or deuterium concentrations in the overall range from 5x10<16> to 5x10<21> molecules/cm<3>, and an optimised geometry of the tapering region is specified as a function of the core diameter of the cylindrical region. <IMAGE>
