Pulsed Nd:YAG laser marking system for wood surfaces

This work reports the development of a complete laser marking system applied to study wood surface marking. In this development, the output pulses of light from a Nd:YAG laser are controlled by positioning them in a desired place and time, according to the image to be printed. The entire process is automated through an interconnection between the laser, a microcontroller and a computer. The main contributions of this work are the use of a specifically pulsed laser, the integration of all parts involved in the marking process and the marking study over a wood surface.
