Infrared-laser-induced periodic surface structure in azo-dye polymer
Second-harmonic and third-harmonic waves that are generated in an azo-polymer form diffraction patterns without any material deformation. The source is a single IR laser beam at λ=1064 nm that is weakly absorbed by the polymer. If the IR power is sufficiently high, laser-induced periodic (700 nm) st...
