A method is proposed for efficient laser modification of fused silica and sapphire by means of a burst of femtosecond pulses having time separation in the range 10-3000 ps. Modification enhancement with the pulse separation increase in the burst was observed on the tens picoseconds scale. It is proposed that accumulated transient tensile strain in the excitation region plays a crucial role in modification by a sub-nanosecond burst.
提出了一种通过一系列飞秒脉冲对熔融石英和蓝宝石进行高效激光改性的方法，这些脉冲的时间间隔在10 - 3000皮秒范围内。在数十皮秒的尺度上观察到随着脉冲串中脉冲间隔的增加，改性增强。有人提出，激发区域中累积的瞬态拉伸应变在亚纳秒脉冲串改性中起关键作用。
