Abstract

Femtosecond laser-generated stress waves play a crucial role in processing transparent materials. However, their dependence on laser pulse energy, a key processing parameter, remains unclear. To investigate this, we employ a pump-probe microscope-polariscope with in situ laser intensity imaging, complemented by multiphysics-multiscale numerical simulations. Our study examines single-shot irradiation inside fused silica using 360-fs, 1030-nm laser pulses with energies ranging from 250 nJ to several μJ. We observe a logarithmic scaling of the principal stress difference, governed by peak intensity clamping, in quantitative agreement with simulations.

熔融石英内飞秒激光产生应力波的脉冲能量标度。

飞秒激光产生的应力波在透明材料的加工中起着至关重要的作用。然而，它们对激光脉冲能量（一个关键的加工参数）的依赖性尚不清楚。为了研究这一点，我们采用了泵浦探针显微镜-偏光镜与原位激光强度成像，辅以多物理场多尺度数值模拟。我们的研究使用360-fs， 1030-nm激光脉冲，能量范围从250 nJ到几μJ，在熔融石英内部进行单次照射。我们观察到主应力差的对数标度，由峰值强度夹紧控制，与模拟定量一致。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
