Results of the experimental and theoretical investigations of CO2 laser-eng
raved cylinders are presented. The processed surfaces of test samples are e
xamined by a phase-stepping laser interferometer, digital microscope, and c
omputer-controlled profilometer. Fourier analysis is made on the patterns p
arallel to the axis of the laser-scribed test ceramic cylinders. The proble
m of the visually observed banding is discussed. (C) 1999 Optical Society o
