Plasmon-less surface enhanced Raman spectra induced by self-organized networks of silica nanoparticles produced by femtosecond lasers

Yves Bellouard, Erica Kathleen Block

Raman spectroscopy is the workhorse for label-free analysis of molecules. It relies on the inelastic scattering of incoming monochromatic light impinging molecules of interest. This effect leads to a very weak emission of light spectrum that provides a sig ...

Non-ablative femtosecond laser exposure of fused silica in the sub-50 fs regime (Conference Presentation)

Yves Bellouard, Benjamin Wesley Mc Millen, Erica Kathleen Block

In the non-ablative regime, femtosecond laser pulse duration is known to affect the nature of the modification induced in the microstructure of fused silica. It has been demonstrated than below 200 fs, two different regimes are found, one at low energy, le ...

Two-phase displacements in microchannels of triangular cross-section

Erica Kathleen Block

Varying microfluidic channel cross-sectional geometry can dramatically alter fluid flow behavior, particularly for capillary-driven flow. Most fabrication techniques, however, are planar and therefore incapable of providing depth-dependent variations in wi ...

Local tuning of fused silica thermal expansion coefficient using femtosecond laser

Yves Bellouard, Pieter Vlugter, Erica Kathleen Block

Femtosecond laser exposure of fused silica in the nonablative regime can lead to various localized bulk modifications of the material structure. In this paper, we show that these laser-induced modifications can be used to tune silica thermal expansion prop ...
