Abstract: A very high power fiber light source can be realized by using a high concentration of doping and by pumping the cladding of the doped fiber. The light that enters the cladding will then enter the core and amplified spontaneous emission will result. With this arrangement, higher power, a broader emission spectrum, and low radiation sensitivity can be achieved. These devices can also be configured as amplifiers.

Abstract: In a known method, a quartz glass preform is produced by supplying a glass-forming base material in liquid form to an injection nozzle of a multi-nozzle flame deposition burner, vaporizing or gasifying the liquid glass-forming base material in the deposition burner, mixing the vaporized or gasified glass-forming base material with a gas containing oxygen under creation of SiO.sub.2 particles in a chemical reaction, deposition of the SiO.sub.2 particles on a substrate under creation of a porous preform and sintering of the preform. In this method, expensive devices such as pumps and ultrasonic vaporizers are needed for the vaporization of the liquid glass-forming base material; in addition, these devices are subject to mechanical wear and chemical attack and furthermore, they require extensive maintenance and due to their size result in a great height of construction. In order to avoid these disadvantages, a method is proposed according to the invention wherein a gas for the creation of a mist is fed to the deposition burner for the vaporization or gasification of the glass-forming base material, resulting in the creation of a low pressure in the area of the injection nozzle orifice. In an apparatus suitable for implementing the method, a vaporizing device comprises a vaporizing nozzle for the supply of a vaporizing gas, said nozzle being located adjacent to the injection nozzle and having an opening which, as seen in the direction of travel of the vaporizing gas, extends in a plane behind the injection nozzle opening.

Abstract: An optical amplifying fiber including a clad, a first core provided inside the clad and containing Ge, a second core provided inside the first core and containing Er and Al, and a third core provided inside the second core and containing Ge. The second core has a refractive index higher than that of the clad, and the first and third cores have refractive indexes each of which is higher than that of the second core. Since the third core having the high refractive index is provided at a central portion, it is possible to make smaller a mode field diameter and hence to improve a conversion efficiency of pumping light into signal light. Further, since the second core contains Al as an amplification band width increasing element, it is possible to sufficiently ensure a wide amplification band width.

Abstract: A master oscillator and power amplifier configuration for a high power cladding-pumped laser structure, and a method of making same, is disclosed. The laser structure comprises a single mode core having at least one oscillator defined therein, and a first and second cladding layer for waveguiding and radiation retention. The core is doped with refractive-index modifying dopants, in addition to ionized rare earth elements. The refractive-index modifying dopants facilitate writing one or more spaced pairs of index gratings in the core, each pair defining an oscillator. Oscillator cavity length is determined by the desired mode spacing and is less than one-half of the single mode core length. The index gratings are formed via a ultraviolet light-induced refractive index change in the core, which index change varies periodically along the core. The periodic variation is created by projecting an interference pattern on the core.

Abstract: Disclosed is a method for the axial building up, in a vertical arrangement, of a hollow cylindrical soot body having no internal support and consisting substantially of silicon dioxide by means of at least one flame hydrolysis build-up burner serving for the soot production. In this method the soot is deposited at the beginning of the build-up onto an auxiliary body, and during the build-up the build-up burner and the growing soot body are rotated relative to one another, and the burner is at the same time held at an unvarying distance from the growing end of the hollow cylinder and centrally above the predetermined cross section of the upwardly growing end of the cylinder wall. The penetration of soot into the interior of the cylinder is prevented by means of a directed gas stream.
