A method and system for generating an optical fiber is provided. The method includes creating a green fiber consisting primarily of a ceramic material and sintering the green fiber with a laser by moving the green fiber through a beam of the laser to increase the density of the fiber after sintering. The system for creating a continuous optical fiber includes an extruder, a processing chamber and a laser. The extruder is configured to extrude a ceramic slurry as a green fiber. The processing chamber is configured to receive and process the green fiber. And, the laser is configured to direct a laser spot on the green fiber exiting the processing chamber to sinter the green fiber.

Methods of producing doped and undoped yttrium aluminum garnet and yttrium aluminum perovskite containing powders and the powders produced thereby are provided. Additionally, methods of forming doped and undoped polycrystalline yttrium aluminum garnet having a mean grain size of between about 1 &#x3bc;m to about 3 &#x3bc;m and the yttrium aluminum garnet produced thereby are provided. The doped and undoped polycrystalline yttrium aluminum garnet may be formed by sintering a compact and subsequently hot isostatically pressing the compact.
