Deep UV generation and direct DNA photo-interaction by harmonic nanoparticles in labelled samples

Sandrine Gerber, Davide Städler, Jean-Pierre Wolf, Solène Marcelle Françoise Marie Passemard, Luigi Bonacina, Daniel Rytz

A biophotonics approach based on the nonlinear optical process of second harmonic generation is presented and demonstrated on malignant human cell lines labelled by harmonic nanoparticles. The method enables independent imaging and therapeutic action, sele ...

Harmonic Nanoparticles for Regenerative Research

Jean-Pierre Wolf, Jérôme Extermann, Luigi Bonacina

In this visualized experiment, protocol details are provided for in vitro labeling of human embryonic stem cells (hESC) with second harmonic generation nanoparticles (HNPs). The latter are a new family of probes recently introduced for labeling biological ...

Tailoring single-cycle electromagnetic pulses in the 2–9 THz frequency range using DAST/SiO_2 multilayer structures pumped at Ti:sapphire wavelength

Christoph Peter Hauri, Jean-Pierre Wolf, Luigi Bonacina

We present a numerical parametric study of single-cycle electromagnetic pulse generation in a DAST/SiO2 multilayer structure via collinear optical rectification of 800 nm femtosecond laser pulses. It is shown that modifications of the thicknesses of the DA ...

Harmonic Nanocrystals for Bio-Labeling: a Survey of Optical Properties and Biocompatibility

Sandrine Gerber, Davide Städler, Jean-Pierre Wolf, Solène Marcelle Françoise Marie Passemard, Jérôme Extermann, Luigi Bonacina, Daniel Rytz, Rachid Hadji

Nonlinear optical nanocrystals have been recently introduced as a promising alternative to fluorescent probes for multi-photon microscopy. We present for the first time a complete survey of the properties of the different nanomaterials proposed to date, de ...

Nonlinear Correlation Spectroscopy (NLCS)

Theo Lasser, Marcel Leutenegger, Iwan Märki, Jean-Pierre Wolf, Noelia Laura Bocchio, Luigi Bonacina, Stefan Geissbuehler

We present a novel concept for optical spectroscopy called nonlinear correlation spectroscopy (NLCS). NLCS analyses coherent field fluctuations of the second and third harmonic light generated by diffusing nanoparticles. Particles based on noncentrosymmetr ...

Spectral phase, amplitude, and spatial modulation from ultraviolet to infrared with a reflective MEMS pulse shaper

Nico de Rooij, Wilfried Noell, Jean-Pierre Wolf, Fabio Jutzi, Jérôme Extermann, Sébastien Lani, Luigi Bonacina

We describe the performance of a reflective pulse-shaper based on a Micro-ElectroMechanical System (MEMS) linear mirror array. It represents a substantial upgrade of a preceding release [Opt. Lett. 35, 3102 (2010)] as it allows simultaneous piston and tilt ...

Design, simulation, fabrication, packaging, and characterization of a MEMS-based mirror array for femtosecond pulse-shaping in phase and amplitude

Nico de Rooij, Wilfried Noell, Jean-Pierre Wolf, Fabio Jutzi, Jérôme Extermann, Sébastien Lani, Luigi Bonacina

We present an in-detail description of the design, simulation, fabrication, and packaging of a linear micromirror array specifically designed for temporal pulse shaping of ultrashort laser pulses. The innovative features of this device include a novel comb ...
