In this work, a Q – switched Nd:YAG laser is used to cut different thicknesses of acrylic sheets with different cutting speeds and laser repetition rates.The obtained results for the transparent sheets show clearly that it is difficult to cut these sheets completely, this is due to the fact that most of the laser power will be transmitted through them, while some will be absorbed causing the heat affected zone (HAZ), which is inversely proportional to the cutting speed.On the other hand, cutting of the black sheets, using the same laser parameters showed that the depth of cut is inversely proportional to the cutting speed and the cutting process is easy.The results showed, also, a linear relation between laser repetition rate and cutting depth. Higher laser repetition rates resulted in an increase in the depth of cut and vice versa.
