摘要
The combined effect of short(picosecond) optical and(nanosecond) electrical pulses on dielectric breakdown is investigated both theoretically and experimentally. It was demonstrated that nanosecond electrical pulses(nsEPs),being applied simultaneously with picosecond optical pulses, reduce the threshold for optical breakdown.Experimental results are discussed with respect to an extended model for opto-electrical-induced breakdown.The newly unveiled effect is expected to play a significant role in spatially confined electroporation and further advances in laser-ablation-based processes while also allowing for measurements of ambipolar diffusion constants.
