Abstract
This paper discusses our activities regarding the development of a laser-manufacturing test bed and
database for laser-material processing conducted under the NEDO (New Energy and Industrial
Technology Development Organization) Project, which undertakes research and development of nextgeneration
laser-processing technology. Since more than 30 years, research and development is being
conducted on laser-material processing, and it has become one of the most precious technologies.
However, laser-material processing is one of the most complex concepts, i.e., it is categorized as an open
nonlinear system far from equilibrium. In this study, we elucidate the physics of light–matter interaction
to realize the new laser-manufacturing world, and control and exploit the dynamics of materials’
response to laser irradiation. The results of this study will determine the optimal values of laser
parameters such as wavelength, pulse width, and repetition rate. A test bed for laser-material processing
is built to confirm the adaptability and usefulness of the newly developed laser system in actual operation
environments.
