利用飞秒双脉冲序列成功地诱导出了偏振相关的周期性纳米结构。这样的纳米光栅结构包括用纳米尺度周期性地调制缺氧。此外，我们还观察到，这种条状氧缺陷区域包括纳米孔。此外，尽管总能量相同，双脉冲序列诱导的纳米孔的平均尺寸是单脉冲序列的两倍大。结果表明，双脉冲串辐照可以获得两倍高的双折射。
The polarization-dependent periodic nanostructure are successfully induced by the femtosecond double-pulse train. Such nanograting structures consist of periodic modulation of oxygen deficiency with nanoscale. Furthermore, we have also observed that this stripe-like oxygen defect regions include nanopores. Additionally, the average size of the induced nanopores by the double-pulse train was twice as large as that of the single-pulse train, despite of the same total energy. As the results, twice higher birefringence can be obtained by the double-pulse train irradiation.
