Bessel beam femtosecond lasers being non-diffractive are well-suited for drilling high aspect
ratio microholes with minor thermal impact. Hereby, the Bessel beams with different non …

We present a flexible approach for generating autofocused aberration laser beams (ALBs) of
different wavelengths based on the diffractive optical element (DOE) design with distinct …

In order to achieve high-resolution micro-machined features, tight focusing is traditionally
adopted in laser micro-machining systems, at the cost of a narrow axial machining range. As …

We present the results of experiments on generation of Hermite–Gaussian modes up to the
third order inclusive using binary-phase diffractive optical elements (DOEs) illuminated by …

Features of laser-assisted warm forming of dual phase steel DP1000 are determined.
Simulation of forming processes with local heating is performed. In the simulation procedure …
