“…In particular, finite-energy Bessel beams (BB) [5] have been the object of intense research and applications in different fields. Thanks to their self-reconstruction property, their elongated focal zone (orders of magnitude longer than the Rayleigh range of a Gaussian beam focused down to the same core dimension) and the capacity of maintaining a smooth longitudinal fluence profile under both linear propagation and nonlinear propagation [6], BB have been used in micromanipulation [7], microscopy [8], micro-and nanostructuring [9][10][11][12][13][14][15][16] and cutting [17][18][19][20] of transparent materials.…”

In this paper, we present a laser etching and drilling technique for thin glass materials based on the use of finite-energy pulsed Bessel beams orthogonally impinging on the sample surface. Thanks to the elongated focal zone of the quasinon-diffractive beam, the laser processing can be performed without scanning the beam position along the thickness of the transparent material sample, but simply moving the sample in the plane orthogonal to the beam. We first present the results of single-shot glass microfabrication performed to identify the optimal laser parameters needed for an efficient internal material ablation. We then describe the micromachining technique used for etching the dielectric material at glass-air interfaces and for generating, without chemical etching, through-holes in thin glasses.

“…As a part of this investigation, a visible plasma plume formed during the Ag ablation (in air and on stable and moving Ag targets in acetone) was recorded with a USB 4000 (Ocean Optics) spectrometer. WLC generation and the possibility of multiple filamentation with Bessel beams was also investigated [32][33][34][35][36]. Surface morphologies of laser-exposed Ag portions in air and acetone under the same experimental conditions were investigated.…”

Ablation of silver targets immersed in double distilled water (DDW)/acetone was performed with first order, non-diffracting Bessel beams generated by focusing ultrashort Gaussian pulses (~2 and ~40 fs) through an Axicon. The fabricated Ag dispersions were characterized by UV-visible absorption spectroscopy, transmission electron microscopy and the nanostructured Ag targets were characterized by field emission scanning electron microscopy. Ag colloids prepared with ~2 ps laser pulses at various input pulse energies of ~400, ~600, ~800 and ~1000 µJ demonstrated similar localized surface plasmon resonance (LSPR) peaks appearing near 407 nm. Analogous behavior was observed for Ag colloids prepared in acetone and ablated with ~40 fs pulses, wherein the LSPR peak was observed near 412 nm prepared with input energies of ~600, ~800 and ~1000 µJ. Observed parallels in LSPR peaks, average size of NPs, plasmon bandwidths are tentatively explained using cavitation bubble dynamics and simultaneous generation/fragmentation of NPs under the influence of Bessel beam. Fabricated Ag nanostructures in both the cases demonstrated strong enhancement factors (>10 6) in surface enhanced Raman scattering studies of the explosive molecule CL

“…This plasma track is indeed the main support for laser energy deposition, before energy is transferred to the lattice and induces thermo-mechanical constraints leading to void nanochannels or to high aspect ratio inscribed microstructures. 8,9 In general, plasma imaging techniques (either time-integrated or time-resolved) provide a unique tool which has been used for the assessment of ultrafast interactions. They are usually holographic reconstructions techniques that make use of a pump and an orthogonally propagating probe.…”

This work aims at highlighting the plasma generation dynamics and absorption when a Bessel beam propagates in glass. We developed a simple diagnostics allowing us to retrieve clear indications of the formation of the plasma in the material, thanks to transmission measurements in the angular and wavelength domains. This technique featured by the use of a single chirped pulse having the role of pump and probe simultaneously leads to results showing the plasma nonlinear absorption effect on the trailing part of the pulse, thanks to the spectral-temporal correspondence in the measured signal, which is also confirmed by numerical simulations
