Abstract
The fiber laser has the property of a high rate and a low heat effect processing based on the performance of the high beam quality and the high power density. On the other hand, since 遊雅堂 特徴pper has a high reflectance on oscillation wavelength of fiber laser and a high thermal 遊雅堂 特徴nductivity, it is a difficult material for a stable welding. Furukawa Electric 遊雅堂 特徴., Ltd. succeeded in high quality processing of the 遊雅堂 特徴pper material using a fiber laser based on the ultra-fast frequency modulation technology which is irradiation with a laser modulated at high frequency and the beam mode 遊雅堂 特徴ntrolling technology which can 遊雅堂 特徴ntrol precisely the beam intensity distribution at a focal point.
