摘要： A front face distance is obtained by measuring the position of a front face of an instrument panel held by an end effecter of a robot. An error on an optical axis, at the position of the front face is obtained based on the front face distance. Based on the error, the position of the instrument panel is adjusted so that a focal point of a laser meets the position at a predetermined depth defined with the front face as the standard. A back face of the instrument panel is irradiated with a laser to form a fine hole of a fragile section.

摘要： Provided is a small-sized laser light generating apparatus capable of oscillating continuous light with a range of wavelengths of about 200 nm or less with stability at high conversion efficiency. Light with wavelength &lgr;1 and light with wavelength &lgr;2 outputted from a first laser light generator and a second laser light generator are introduced into a first resonator and a second resonator, respectively, and then a nonlinear optical device included in both the first and second resonators generates light with wavelength &lgr;3 through sum-frequency mixing of these two incoming light beams. The light with the wavelength &lgr;1, the light with the wavelength &lgr;2 and the light with the wavelength &lgr;3, which are spatially separated from one another, enter into and exit from the nonlinear optical device and have different optical paths. The light with the wavelength &lgr;1 and the light with the wavelength &lgr;2 are set so that the optical axes thereof do not perfectly match in the nonlinear optical device, and an incident angle or an exit angle of at least one of the two light beams is set at a Brewster angle, whereby reflection loss can be further reduced.
