Surface modification of elastomerrcarbon composite by Ndq:YAG laser and KrF excimer laser ablation

Excimer laser ablation of an elastomer composite containing carbon black produced conical microstructures on the ablated surface upon irradiation with the second harmonic of Ndq:YAG laser. Based on studies by scanning electron microscopy and quadrupole mass spectrometry, the mechanism for the conical structure formation was discussed by comparison of the formation of cone-like microstructures produced by KrF excimer laser ablation. q1999 Elsevier Science B.V.
