FLEXIBLE OPTICAL GRADED-INDEX PROFILE FIBER FOR TRANSMISSION OF LASER RADIATION WITH HIGH OUTPUT WITH SUBSTANTIAL PRESERVATION OF THE MODE STRUCTURE

摘要

A flexible optical multimode fiber for the transmission of laser radiation with high radiation output is described in which the mode structure of the radiation is substantially preserved. The fiber is especially suited for transmitting radiation in Gaussian modes. The dimensioning of the fiber is indicated, and a composition for fibers for the spectral region of about 250 nm to 2 microns is proposed.
