摘要
Image drawing using a laser system has been attempted by Segmented Pixel Drawing (SPD) method and Laser Plastic Coloring (LPC) method in our laboratory. Laser dot processing by a short pulse oscillation of a CO2 laser is used for these laser methods. Stable short pulse oscillation is required for an accurate image drawing. That oscillation has a tendency to be unstable because of its long oscillation interval. A tickle pulse is known as one of a technique which is conventionally used for a continuous pulse oscillation of a CO, laser in order to make rising rate of laser oscillation quick. In this study, this tickle pulse has been improved and applied to the short pulse oscillation in order to stable short pulse oscillation and high accurate laser dot processing. In the result, processed dots are appeared bigger with less variation in their sizes with the improved tickle pulse case compared with the conventional case. Short pulse oscillation is stabilized by these improved tickle pulse. Reproducibility and accuracy of the SPD method and LPC method might be realized by this stabilized dot processing.
