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.

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 an optical amplifier (TDFA) having a configuration which enables to reduce temperature dependence of the gain with reduced power consumption and simple control. The optical amplifier includes, in the order from an input port to an output port, an optical isolator, an optical coupler, an optical amplification fiber, an optical coupler, an optical isolator, an optical gain equalizing filter, a variable optical attenuator, an optical isolator, an optical coupler, an amplification fiber, an optical coupler, and an optical isolator. At least a core region of the optical amplification fiber is doped with Tm element, and signal light in a predetermined wavelength range is amplified by supply of pumping light. The gain equalizing fiber has a loss spectrum which shifts toward the short wavelength side as the temperature of the optical waveguide is higher, thereby equalizing the optical amplification gain of the signal light in the optical amplification fiber.

摘要： Inputted multiplexed optical signal is separated by an optical branching section into C-band multiplexed optical signal and L-band multiplexed optical signal, and the C-band multiplexed optical signal and L-band multiplexed optical signal are optically amplified by a C-band optical amplifier and an L-band optical amplifier, respectively. The amplified optical signals are combined by an optical combiner, and thus combined optical signal is outputted therefrom. The backward ASE light generated in the L-band optical amplifier upon optical amplification is blocked by an optical filter disposed between the optical amplifier and the optical branching section, so as to be prevented from traveling backward and being inputted to and amplified by the C-band optical amplifier, whereby the deterioration of noise characteristics is restrained.
