摘要： Aims are to provide a tubular-body residual-stress improving apparatus and an adjustment method thereof capable of adjusting irradiation position with favorable reproducibility, even when an optical fiber is eccentric. In the tubular-body residual-stress improving apparatus, an optical control unit (5) includes a rotational hold mechanism (9) for holding an optical fiber (6) in a manner that the optical fiber (6) is rotatable in a circumferential direction of the optical fiber (6), and, if a position of an intensity peak of the laser beam from the optical fiber (6) in an axial direction of the tubular body (2) is offset from the center of an irradiation profile, a position at which the optical fiber (6) is held in the circumferential direction is adjusted by the rotational hold mechanism (9) so as to eliminate the offset or to minimize an influence of the offset.

In the tubular-body residual-stress improving apparatus, an optical control unit (5C) includes one pair of mirrors (21, 22) being disposed at a final stage of an optical system for a plurality of laser beams (P1-Pn) to be sharable and disposed in such a way that the mirrors are placed respectively at both sides, in the circumferential direction of the tubular body (2), of a final optical path of the laser beams to the tubular body (2), and another pair of mirrors (23, 24) being disposed at final stage of the optical system for the laser beams at both ends and disposed in such a way that the mirrors are placed respectively at both sides, in an axial direction of the tubular body (2), of final optical paths of the laser beams at both ends to the tubular body (2). Two pairs of mirrors (21-24) reflect inwards a skirting portion of the corresponding laser beam in the circumferential and axial direction of the tubular body (2) so as to irradiate the tubular body (2) with the laser beams.

摘要： A nonlinear optical crystal device, a wavelength conversion element, is surrounded with a heat sink having cooling fins. Cartridge heaters for uniformly heating the nonlinear optical crystal device are arranged in the heat sink, and the temperature of the cartridge heater is regulated by a heater controller. Laser light is input into the nonlinear optical crystal device, and delivered therefrom after its wavelength is converted into a shortened wavelength. When the repetition frequency of laser light is high, heating by the heaters is stopped, and cooling is effected with the heat sink. When the repetition frequency of laser light is low, heating by the heaters is carried out to maintain the temperature of the nonlinear optical crystal device to be a temperature at which a conversion efficiency is satisfactory.
