LASER APPARATUS AND A METHOD OF FABRICATING THEREOF

摘要

A solid state waveguided structure a core fabricated of a lasingmedium, diffusion-bonded to a cladding fabricated of a laser-inactivematerial. The meduim of the core comprises a lutetium-aluminum-garnetmaterial doped with ions of ytterbium, lutetium-aluminum-garnet material doped with ions of neodymium, and lutetium-aluminum-garnet materialdoped with ions of thulium, and the laser-inactive material of the claddingcomprises an yttrium-aluminum garnet material. A method of fabricating a solid state waveguided structure with improved characteristics comprisingusing a combination of a trivalent ions of ytterbium-doped lutetium-aluminum-garnet core and a yttrium-aluminum-garnet cladding.
