The PolySense team has just published a new article on Optics Express reporting on incubation effect on the laser ablation threshold of quartz, after multi-shot irradiation with femtosecond pulses. A strong decrease of the multi-pulse ablation threshold with the number of pulses was found due to incubation. Moreover, the influence of the repetition rate was Leggi di piùNew Publication on Optics Express[…]
