The light–energy coupling during femtosecond laser processing of glass is mediated by non-linear ionization mechanisms through the formation of an electron plasma. Its transient optical properties provide information about the density, temperature

Nonlinear processing of glass using femtosecond laser pulses has been shown as a reliable method for producing photonic devices. To optimize the writing of optical waveguides and harness the true power of fs-laser modification, it is imperative that

We have investigated the effect of the laser wavelength on the fabrication of optical waveguides and tracks of modified material via direct laser writing inside fused silica. The size of the laserinscribed tracks, the material modification thresholds

Femtosecond (fs)-laser processing of CdSxSe1-x-doped borosilicate glasses was investigated to create hybrid multiscale structures consisting of semiconductor nanocrystals embedded in microscopic domains defined by the laser irradiation. Laser process

We have investigated the permanent refractive index changes inside fused silica glass after laser inscription of waveguides using ultrashort laser pulses at different wavelengths. To this end the laser frequency was detuned using an optical parametri

Laser tweezers Raman spectroscopy was used to detect the cellular response of Escherichia coli cells to penicillin G-streptomycin and cefazolin. Time-dependent intensity changes of several Raman peaks at 729, 1,245, and 1,660 cm −1 enabled untreate

Recent advances in the application of glassy materials in planar and fiber-based photonic structures have led to novel devices and components that go beyond the original thinking of the use of glass in the 1960s, when glass fibers were developed for

We report the analysis of the vibrational modes of intranuclear protein inclusions isolated from the brain of human subjects with the Fragile X-associated tremor/ataxia syndrome (FXTAS). In this preliminary study, Raman spectra of optically trapped i

Tight focusing of ultrashort (∼100 fs) infrared laser pulses of moderate energy (typically 1–10 μJ) into a glass results in very high, localized (in space and time) intensities, in excess of 10 14 W/cm 2 . Under these conditions the laser–mate

The permanent refractive index change induced by ultrashort laser pulses in zinc phosphate glasses has been investigated both at the surface and in bulk. At the sample surface, irradiations have been performed by using loosely focused single fs-laser
