摘要： A conventional diffractive optical element (DOE), which consists of repetition of a unit pattern , has an advantage of applicability of the Fast Fourier Transform algorithm to calculate diffraction beam spots intensities on lattice points on an image plane. But, the conventional DOE has a drawback of impossibility of diffracting a laser beam off the lattice points. This invention designs a DOE by giving arbitrary complex amplitude transmittance {tmn} to every pixel (m, n), calculating actual Fourier transform from {tmn} to intensity W(α, β), and obtaining intensity of a diffraction beam directing in any α and β direction. Since α, β are not necessary to be on lattice points, the FFT is of no use. Angular resolutions U and V satisfy inequalities U

摘要： A laser beam condensing device which can be manufactured at low cost by using reflecting mirrors which can be machined at low cost. The device is capable of condensing a laser beam to a high energy density while eliminating any optical path difference, even if the optical axis of the incident beam strays. This device includes a first and a second reflecting mirror. An incident laser beam is deflected by these mirrors in the same direction. One of the two mirrors is a toroidal mirror, while the other is a spherical, cylindrical or toroidal reflecting mirror. The mirror surfaces of the two reflecting mirrors are machined so that the second reflecting mirror can cancel out any wave front aberrations of the laser beam reflected by the first reflecting mirror.

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： Purpose: To provide a laundry system with improved customer services by utilizing portable information terminals having a radiocommunication function such as mobile phones and PHS. Constitution: Upon completion of washing or drying in a laundry machine 102, data for notifying the user of the completion of the treatment are transmitted to the user's mobile phone 100. In addition, when a prescribed time, for example, 10 minutes, elapses after washing or drying finished, a request for permission to unload the laundry is transmitted to the user's mobile phone 100 so as to ask the user whether the clothes can be taken out from the laundry machine 102 or not. The system charges the user when a prohibition response is sent back or there is no response to the request for permission to unload the laundry.
