Non-Gaussian spatial intensity distribution beams used in laser micro- and nano-machining find many applications. For instance, Bessel beams, having a small diameter and a very long focal zone, allow the fabrication of high aspect ratio modifications in transparent materials. Higher-order Laguerre–Gauss modes are used in particle manipulation and even for multiplexing in optical communication. The temporal intensity distribution of a pulse is mostly overlooked or fixed to Gaussian shape distribution. However, pulse-shaped beams could improve the same fields of particle manipulation as optical traps, or the laser manufacturing. In this paper, we demonstrate a method of constructing a helical spatiotemporal intensity distribution beam the rotation of which in time can be varied. We demonstrate the analytical and numerical results and show an experimental realization of such a structure.

Šiame darbe tiriama greitai laike besisukančio interferencinio pluošto struktūra ir jo erdviniai parametrai. Tokio tipo struktūros yra realizuojamos suvedant du koherentinius pluoštus su topologiniu krūviu / orbitiniu judesio kiekio momentu. Jeigu jų topologiniai krūviai skiriasi, gaunamas pluoštas su maksimumų skaičiumi, lygiu abiejų pluoštų topologinių krūvių skirtumui. Toks pluoštas laike yra statiškas, norint indukuoti jam sukimąsi reikia laike moduliuoti vieno iš pluoštų fazę. Tai galima atlikti elektrooptiniais ar akustooptiniais moduliatoriais, tačiau tokie sprendimai lemia sąlyginai lėtą sukimąsi. Šiame darbe pademonstruotas laike moduliuoto spiralinio intensyvumo pasiskirstymo pluošto, kurio sukimąsi laike galima keisti, formavimo metodas. Tai įgyvendinama interferuojant du kolinearius čirpuotus ir laike pastumtus impulsus. Pateikiami analitiniai ir skaitiniai rezultatai bei parodomas eksperimentinis tokios struktūros realizavimas. Skirtingai nuo ankstesnių darbų [28, 29], čia parodoma realizacija nelyginių topologinių krūvių atvejais, kai nėra simetrijos apie nulį. Tikėtina, kad pluoštas su laikine moduliacija pikosekundinėje skalėje turės teigiamo poveikio šiluminiam režimui šviesai sąveikaujant su medžiaga.
