capabilities to laser material processing. One of the areas which benefited the most due to …

The ever-growing trend of device multifunctionality and miniaturization puts enormous
burden on existing manufacturing technologies. The requirements for precision, throughput …

We propose and explore a physical mechanism for the stabilization of the complex
spatiotemporal dynamics in arrays (bars) of broad area laser diodes taking advantage of the …

We propose and experimentally demonstrate femtosecond direct laser writing with Bessel
beams for the fabrication of photonic crystals with spatial filtering functionality. Such filters …

Microchip lasers are very compact and efficient coherent light sources; however, their
applications are restricted due to poor beam quality and limited brightness, especially in …

Optical aberrations are a type of optical defect of imaging systems that hinder femtosecond
direct laser write machining by changing voxel size and aspect ratio in different sample …

The goal and essential parameter of laser light conversion is achieving emitted radiation of
higher brightness. For many applications, the laser beam must have the highest available …

Spatial filtering is an important mechanism to improve the spatial quality of laser beams.
Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used for …

Broad aperture semiconductor lasers usually suffer from low spatial quality of the emitted
beams. Due to the highly compact character of such lasers, the use of conventional …

We propose and experimentally demonstrate spatial filtering by photonic crystals in a Bragg
configuration. Compared to the Laue configuration, where spatial filtering was already …
