We investigated the laser ablation of an elastomer composite with picosecond‐ (ps‐) and femtosecond‐ (fs‐) pulsed UV lasers (ps‐laser: λ = 263 nm, τ = 8 ps; fs‐laser: λ = 248 nm, τ = 500 fs). Upon laser irradiation, a unique microstructure on the surface of the elastomer composite (acrylate polymer) containing carbon black (particle size: 18–30 nm) was observed. The laser‐ablated surfaces were analyzed by scanning electron microscopy (SEM) and X‐ray photoelectron spectroscopy (XPS). The formation mechanism is discussed in terms of thermal effects induced by the different pulse durations of the lasers.
