{ "DOI": "10.2961/jlmn.2016.03.0012", "abstract": "We investigated modifications and the temporal evolution of the morphology in the photoexcited region inside diamond single crystal after photoexcitation by tightly focused fs laser pulses. We found that double-pulse irradiation with 200-400 fs laser pulses was able to induce a permanent modification in the photoexcited region, while single-pulse irradiation with 100-300 fs laser pulses was not. The modification by double-pulse irradiation became larger for a longer time-difference between the two pulses in the range from 1 ps to 10 ps. The morphology change observed by a pump-probe optical microscope showed that the photoexcited region by double-pulse irradiation was smaller than by single-pulse irradiation, even for the same total pulse energy, with the amplitudes of the laser induced-stress waves being the same. This observation suggests that the photoinduced plasmas by double-pulse irradiation was localized in a smaller region than that by single-pulse irradiation, and the difference in plasma distribution could be the origin of the permanent modification.", "author": [ { "family": "Sakakura", "given": " Masaaki" }, { "family": "Okada", "given": " Takuro" }, { "family": "Bharadwaj", "given": " Vibhav" }, { "family": "Sotillo", "given": " Belen" }, { "family": "Eaton", "given": " Shane M." }, { "family": "Ramponi", "given": " Roberta" }, { "family": "Serpenguzel", "given": " Ali" }, { "family": "Gokay", "given": " Ulas S." }, { "family": "Shimotsuma", "given": " Yasuhiko" }, { "family": "Miura", "given": " Kiyotaka" } ], "container_title": "JOURNAL OF LASER MICRO NANOENGINEERING", "id": "53391", "issue": "3", "issued": { "date-parts": [ [ 2016, 1, 1 ] ] }, "page": "346-351", "title": "Modification and Dynamics inside Diamond by Femtosecond Laser Double-Pulse Irradiation", "type": "article-journal", "volume": "11" }
