摘要： The present invention relates to a MOPA light source capable of obtaining pulse output by wavelength-conversion of pulse light of fundamental light wave using a simple configuration, and suppressing optical output using a simple method when processing is not performed. The fundamental light wave outputted from a seed light source is amplified in an optical amplification fiber. The amplified fundamental light wave is inputted to one end of a passive optical fiber, and propagates in the passive optical fiber. In the passive optical fiber, stimulated Raman scattering occurs upon propagation of the fundamental light wave. The light of fundamental light wave and light of stimulated Raman-scattered components are outputted from the other end of the passive optical fiber. The light outputted from the passive optical fiber is collimated by a lens, and is then inputted to a branching filter. The light inputted to the branching filter is wavelength-separated into light of stimulated Raman-scattered components having wavelengths longer than that of the fundamental light wave, and light having wavelengths equal to or less than that of the fundamental light wave.

摘要： The present invention relates to an optical gain waveguide having excellent gain flatness in C-band, and excellent tolerance against variations of a pumping light wavelength as well, and a method of controlling the same. The optical gain waveguide includes an optical waveguide region which is doped with Er element which can be pumped by irradiating pumping light with a wavelength of 976 nm or less, or a wavelength of 981 nm or more. A population inversion of Er is optimized so that a gain variation in the C-band becomes minimum, by the irradiation of the pumping light. At this time, a relative gain variation of the optical gain waveguide, which is defined by a peak gain value and a minimum gain value in the wavelength region of 1,530 nm to 1,560 nm becomes smaller than 11.5%. In addition, in the optical gain waveguide, a width of wavelength range producing the relative gain variation smaller than 11% is 36 nm or more.

摘要： The present invention relates to a laser processing method and laser processing apparatus for enabling improvement and maintenance of homogenization of a beam intensity distribution in an irradiated region. The laser processing apparatus comprises, at least, an ASE light generation section for emitting ASE light, and a homogenizer for splitting the ASE light into multiple beams. The ASE generation section for emitting the ASE light as processing laser light is provided, and whereby the deterioration of homogenization due to inter-beam interference is suppressed. The homogenization of beam intensity distribution is improved by locating a condenser lens relative to an object such that the object is shifted from a focus position of the condenser lens in the homogenizer, by intentionally deteriorating a beam quality M2 of the ASE light itself emitted from the ASE light generation section to about 2 to 10, or by a combination of these, in laser processing.

摘要： The present invention relates to a fouling removing method which removes a fouling, comprised of a chemical compound containing carbon, on an object surface by laser light irradiation. The fouling removing method irradiates the fouling on the object surface with laser light while blowing a supporting gas on this area. This structure allows the supporting gas and a fouling material to react with each other when burning the fouling by laser irradiation, so as to generate a carbon-containing gas, and the supporting gas to blow away carbonized residues generated on the object surface. This drastically reduces the carbonized residues on the exposed surface of the object having removed the fouling.
