Laser ablation of a homologous series of four tailor-made UV-sensitive aryltriazene polymers with an increasing content of photodecomposible chromophore units has been studied with a XeCl excimer laser (emission wavelength 308 nm). Irradiation induces a photolytic cleavage of the aryltriazene chromo
Irradiation of some poly(N-vinylcarbazole) films with a 248 nm excimer laser resulted in their ablation, giving an etched hole with a submicrometer depth. A characteristic periodic pattern and small particles with diameter of the order of submicrometers were formed in the etched area. This ablation
