Wakefields Generated by a Tightly Focused Laser Beam
Wakefields generated by a tightly focused laser beam (w0 λp ≡ 2πc/ωp) are characterized by a region of total electron cavitation near the head of the laser pulse, followed by a highly localized region of high electron density. The accelerating field maximizes at a spot size significantly less than λp. The focusing fields are generally larger than the accelerating field, and exhibit complex phas...

متن کاملFirst-order strong-field QED processes in a tightly focused laser beam
In a previous article [Phys. Rev. Lett. 117, 213201 (2016)] we have determined the angular resolved and the total energy spectrum of a positron produced via nonlinear Breit-Wheeler pair production by a high-energy photon counterpropagating with respect to a tightly focused laser beam. Here, we first generalize the results in that article by including the possibility that the incoming photon is ...
متن کاملMaterials processing with a tightly focused femtosecond laser vortex pulse.
In this Letter we present the first (to our knowledge) demonstration of material modification using tightly focused single femtosecond laser vortex pulses. Double-charge femtosecond vortices were synthesized with a polarization-singularity beam converter based on light propagation in a uniaxial anisotropic medium and then focused using moderate- and high-NA optics (viz., NA=0.45 and 0.9) to abl...
متن کاملFocused Ion Beam Based Three-Dimensional Nano-Machining
In recent days, the micro/nano machining becomes an important process to fabricate micro/nano scale dimensional patterns or devices for many applications, especially in electrical and electronic devices. There are two kinds micro-machining in use. i) bulk micromachining, ii) surface micro-maching. In the case of bulk micromaching, the structures can be made by etching inside a substrate selecti...
