Femtosecond laser micromachining in azopolymer films
Full text
In this work, we investigated femtosecond laser micromachining in both poly(methyl methacrylate) (PMMA) and PMMA doped with the azoaromatic compounds Disperse Red 1 (DR1) and Disperse Red 13 (DR13). These compounds are particularly interesting due to their linear and nonlinear optical properties.
