A new relativistic vortex cutter driven by the Laguerre-Gaussian (LG) mode is carried out for first time in three-dimensional particle-in-cell simulations. Studies show that electric fields periodically concentrate and emanate within every laser wavelength reflected circularly polarized LG_{p}^{l} (p=0, l=1, σ_{z}=-1) laser, which works just like a cutter, resulting ultrashort collimated electron cluster with constant period space. single particle model given verifies formation has close...
Discriminative internal imaging for different chip layers can pinpoint the location of critical defect in flip chips, yet existing methods face challenges in-line to identify defects or structures from sub-surface within silicon substrate and their underlying coating. To address these challenges, we develop verify layered elasto-optic models photoacoustic remote sensing microscopy (PARS) that distinguish multi-layers a single device flip-chip wafer inspection. A finite-difference time-domain...
Crater-like structures are experimentally studied with an ultrashort, ultraintense laser pulse intensity of 1.5 × 1018 W/cm2, irradiating borosilicate glass targets, which extends laser-induced craters to the region relativistic intensities. The morphology crater-like is measured accurately using a three-dimensional scanning confocal microscope and electron microscope. experimental results indicate that circular bowl shape formed depth-to-diameter ratio about 1/5, similar meteorite impact...
An ultra-short and ultra-intense optical vortex array (OVA) is generated when two intense counter-propagating Laguerre–Gaussian (LG) pulses with [Formula: see text]-polarization impinge on solid thin targets. In this paper, we propose a method for generating an OVA of high intensity, short wavelength, high-order mode. Three-dimensional (3D) particle-in-cell (PIC) simulation results demonstrated that the harmonics interfered each other in transmitted area. These interference patterns...
