The effect of UV-laser radiation on four species of hardwoods grown in Hungary has been studied by IR spectroscopic method. The monitorings showed, that not only those changes appear in the DRIFT difference spectrum which have been formerly observed using traditional UV-sources (increase in the range of 1710-1770 cm-1, spectral dip at 1510 and 1276 cm-1), but our results show three additional absorption dip around 1396, 1465 and 1539 cm-1 and the enhancement of absorption around 1122 cm-1 which have not been reported in the literature yet. At the same time it turned out that the enhancement of absorption close to 1710 cm-1 is not as important as was thought earlier.
