Abstract

We applied two types of laser to examine the photodegradation of wood and to color the wood with light irradiation and heat treatment. The relative intensities of XeCl-laser-irradiated wood at 1510 cm-1 and 1724 cm-1 calculated from DRIFT spectra changed larger than KrF-laser-irradiated one. In addition, the changes in color by irradiation with XeCl-laser were also more pronounced than those with KrF-laser. By heat treatment after laser-irradiation, the color of the wood irradiated with XeCl-laser changed greater than that with KrF-laser. Therefore, it was thought that UV-B region is more effective for application of laser to a new coloring method with light and heat.
