摘要： In order to obtain a weld bead having a good outer appearance with little splash of sputters or the like and a sufficient shearing force, there is provided a flash lamp control section for controlling flash lamps so as to generate two rectangular waves in a pulse wave form at every cycle of a pulse laser beam generated by a pulse YAG laser during the irradiation of the pulse laser beam on coated metal materials. The flash lamp control section is adapted to control a relationship between a peak power and a pulse width of a first rectangular wave and a peak power and a pulse width of a second rectangular wave in predetermined ranges. Under the control of the flash lamp control section, the pulse laser beam generated by the pulse YAG laser is irradiated to the coated metal materials thereby carry out the irradiating operation.

摘要： A laser light, whose wavelength is to be measured, is introduced into an etalon, a concentric circular interference stripe derived from the etalon is irradiated onto a one-dimensional photodetector array and a diameter of the interference stripe is measured to measure the wavelength of the laser light. Alternatively, if a reference laser light of known wavelength is introduced into the etalon, as described above, a wavelength measurement of extremely high accuracy can be made without being affected by positional deviations of the optical system.

摘要： A discharge exciting excimer laser device comprises a pair of main discharge electrodes, a dielectric and an auxiliary electrode. The dielectric is in a cylindrical form and has a side opposed to one of the main discharge electrodes, which side is formed into a flat plate-like portion. The auxiliary electrode is embraced within the dielectric leaving a space and is opposed to one of the main discharge electrodes with the flat plate-like portion of the dielectric sandwiched therebetween. Such a construction increases laser output and improves insulating performance.
