AI 中文摘要
我们报告了在利用蓝宝石晶体和蒸馏水、由中心波长为800 nm的飞秒激光激发的丝状化实验中，分析脉冲横向强度分布时复本对称破缺（RSB）表现形式的实验观测与表征。RSB源于自聚焦与等离子体散焦之间的竞争，受等离子体通过多光子激发产生的非线性折射率局部涨落影响，这种涨落随后促进了模式间的阻挫。我们的结果不仅证实了多丝化中存在玻璃态光子态（如先前报道[W. Ettoumi, J. Kasparian, and J. Wolf, "Spin-glass model governs laser multiple filamentation," Phys. Rev. Lett., vol. 115, no. 3, pp. 033902, 2015]所述），而且在单丝产生以及伴随锥形发射的丝状化中也存在。这些发现通过建立与磁性的联系，并强调超快光学现象中光的玻璃态行为，增进了对统计非线性光学的理解。
英文摘要
We report the experimental observation and characterization of Replica Symmetry Breaking (RSB) manifestation while analyzing the transverse intensity profile of pulses in filamentation experiments using sapphire crystal and distilled water, excited by a femtosecond laser centered at 800 nm. The RSB arises from the competition between self-focusing and plasma defocusing, subject to local fluctuations in the nonlinear refractive index generated by plasma via multiphoton excitation, which subsequently promotes frustration among modes. Our results confirm the existence of glassy-like photonic states not only in multifilamentation, as previously reported [W. Ettoumi, J. Kasparian, and J. Wolf, "Spin-glass model governs laser multiple filamentation," Phys. Rev. Lett., vol. 115, no. 3, pp. 033902, 2015], but also in the generation of a single filament and in filamentation accompanied by conical emission. These findings improve the understanding of statistical nonlinear optics by establishing connections with magnetism and highlighting the glassy-like behavior of light in the context of ultrafast optical phenomena.
