Materials with relatively small refractive indices (n< 2), such as glass, quartz, polymers,
some ceramics, etc., are the basic materials in most optical components (lenses, optical …

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 …

Dielectric microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

During the last decade, new unusual physical phenomena have been discovered in
studying the optics of dielectric mesoscale particles of an arbitrary three-dimensional shape …

The diffraction limit is a fundamental barrier in optical science and engineering. It limits the
minimum feature size in surface patterning technologies, such as lithography and laser …

We report the phenomenon of ultra-enhanced backscattering of visible light by nanoparticles
facilitated by the 3-D photonic nanojet??? a sub-diffraction light beam appearing at the …

Water is always present in laser processing in air: as vapor, condensate or adsorbate. Water
is the working environment in underwater processing—but it can also be added on purpose …

We report the direct experimental observation of photonic nanojets created by single latex
microspheres illuminated by a plane wave at a wavelength of 520 nm. Measurements are …

The size parameter q= 2π R/λ in spheres with a radius R=(2–3) λ (λ is the radiation
wavelength) is on the order of 10. Strong Mie resonances () are observed in these …

Laser precision engineering is being extensively applied in industries for device
microfabrication due to its unique advantages of being a dry and noncontact process …
