    Abstract: Disclosed is a method of forming a doped glass article. Heated glass particles are deposited on a mandrel where they adhere together to form a porous glass preform having interconnective pores. The mandrel is removed to form a tubular preform having an axial aperture. The preform is suspended in a consolidation furnace by a gas conducting handle having a dopant containing chamber. As the handle and preform are heated, there is flowed through the chamber a gas that reacts with the heated dopant to form a reactant gas that flows into the aperture and into pores, whereby a dopant is incorporated into the porous glass preform. The doped preform is heat treated to consolidate it into an elongated non-porous glass body containing the dopant. The glass body can be provided with cladding glass and drawn into an optical fiber.

    Abstract: A side of a polygonal cross-sectioned glass laser rod core may be clad by applying a slab of a suitable cladding glass material thereto. The fusing of the slab to the core without the formation of entrapped gas bubbles therebetween is accomplished by allowing the slab to rest in essentially line contact with the side of the core at the end adjacent a suitable drawing furnace. The other end of the slab is spaced away from the core material. Means is provided for urging the slab of cladding material toward the side of the encore such that as the core and cladding material are drawn within the drawing furnace, the line of contact between the core and cladding gradually traverses the length of the core and cladding thereby forcing any gas out of the space which exists between the core and cladding to provide a bubble-free interface in the resulting clad glass laser rod.

    Abstract: The invention relates to the production of light-amplifying optical material. Liquid reactant (10) is atomized into droplets (15) using a high velocity gas (20). The droplets (15) are subsequently introduced into a flame (100). Reactants (10, 30) are oxidized in the flame (100) and condensed by forming small particles (50). At least a fraction of said particles (50) is collected and fused to form optical waveguide material, which is subsequently drawn to form an optical waveguide (750). According to the invention, the velocity of the atomizing gas (20) stream is in the range of 0.3 to 1.5 times the velocity of sound. The high velocity enhances atomization and increases reaction rates in the flame (100). The residence times are reduced to such a degree that unwanted phase transformations in the produced particles (50) are substantially minimized. Consequently, very homogeneous material is produced. Especially, in the production of erbium-doped silica, low percentage of clustered erbium ions is achieved.

    Abstract: PURPOSE: An optical fiber for an optical amplifier and a manufacturing method thereof are provided to reduce the manufacturing cost by doping a core layer with a mixed solution of rare earth and metal ions using a solution doping method. CONSTITUTION: In order to manufacture an optical fiber using MCVD(Modified Chemical Vapor Deposition), a clad layer and a second core layer are formed in a silica substrate tube(S10). A first core layer is formed on an inner surface of the second core layer(S20). The first core layer forms a partially-sintered layer that provides a host with respect to a Tm¬3+ ion and a metal ion. A mixed solution of the Tm¬3+ and metal ions is uniformly doped on the first core layer(S30). After completing the doping of the mixed solution, an optical fiber is manufactured by wire-drawing a glass rod containing the Tm¬3+ and metal ions(S40).

    Abstract: 본 발명은 빛-증폭 광학 재료의 제조에 관한 것이다. 액체 반응물 (10)이 고속 기체 (20)를 이용하여 점적 (15)으로 분무된다. 상기 점적 (15)은 후속하여 불꽃 (100) 내로 도입된다. 불꽃 (100) 내 반응물 (10, 30)이 산화되고, 소형 입자 (50)를 형성시킴으로써 응축된다. 상기 입자 (50)의 적어도 일 분획이 수거되고 용융되어 광 도파관 재료를 형성한 다음, 이것은 후속하여 광 도파관 (750)을 형성하도록 인발된다. 본 발명에 따르면, 분무 기체 (20) 스트림의 속도가 음속의 0.3 내지 1.5배의 범위 내에 있다. 고속은 분무를 증진시키고, 불꽃 (100) 내에서의 반응 속도를 증가시킨다. 체류 시간은, 생성된 입자 (50) 내에서의 원치 않는 상 변이가 실질적으로 최소화되도록 하는 정도로 감소된다. 결과적으로, 매우 균질한 재료가 제조된다. 특히, 에르븀-도핑된 실리카의 제조에 있어서, 적은 퍼센트의 클러스터된 에르븀 이온이 달성된다.
