During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the
subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice …

Axicon is a versatile optical element for forming a zero-order Bessel beam, including high-
power laser radiation schemes. Nevertheless, it has drawbacks such as the produced …

Adaptive optics are becoming a valuable tool for laser processing, providing enhanced
functionality and flexibility for a range of systems. Using a single adaptive element, it is …

Laser processing implies the generation of a material function defined by the shape and the
size of the induced structures, being a collective effect of topography, morphology, and …

Non‐Gaussian beam profiles such as Bessel or annular beams enable novel approaches to
modifying materials through laser‐based processing. In this review paper, properties …

Controlling the propagation of intense optical wavepackets in transparent media is not a
trivial task. During propagation, low-and high-order non-linear effects, including the Kerr …

Laser direct writing is a widely employed technique for 3D, contactless, and fast
functionalization of dielectrics. Its success mainly originates from the utilization of ultrashort …

The unique characteristics of ultrafast lasers have rapidly revolutionized materials
processing after their first demonstration in 1987. The ultrashort pulse width of the laser …

Ultra-fast femtosecond (fs) lasers provide a unique technological opportunity to precisely
and efficiently micromachine materials with minimal thermal damage owing to the reduced …

We report femtosecond laser micromachining of micron-size curved structures using tailored
accelerating beams. We report surface curvatures as small as 70 μm in both diamond and …
