Measurement and Shaping of Biphoton Spectral Wave Functions

In this work we present a simple method to reconstruct the complex spectral wave function of a biphoton, and hence gain complete information about the spectral and temporal properties of a photon pair. The technique, which relies on quantum interference, i ...

Ablation device and method for subsurface biological tissue ablation

Demetri Psaltis, Jae-Woo Choi, Alexandre Goy, Thomas Jean Victor Marie Lanvin

The present invention relates to a subsurface laser-induced optical breakdown (LIOB) ablation system including an optical source for providing optical pulses and an optical waveguide for guiding the optical pulses to a subsurface target biological tissue s ...

Demonstrating the saturation of stimulated Brillouin scattering by ion acoustic decay using fully kinetic simulations

Stephan Brunner

The saturation of stimulated Brillouin scattering (SBS) by the decay to turbulence of the ion acoustic wave (IAW) that participates in the three-wave SBS interaction is demonstrated using a quasinoiseless one-dimensional numerical solution to the Vlasov-Ma ...

Temporal solitons in optical microresonators

Tobias Kippenberg, Victor Brasch, Tobias Herr, John David Jost

Temporal dissipative solitons in a continuous-wave laser-driven nonlinear optical microresonator were observed. The solitons were generated spontaneously when the laser frequency was tuned through the effective zero detuning point of a high-Q resonance, wh ...

Mode Spectrum and Temporal Soliton Formation in Optical Microresonators

Tobias Kippenberg, Victor Brasch, Tobias Herr, John David Jost

The formation of temporal dissipative solitons in optical microresonators enables compact, high-repetition rate sources of ultrashort pulses as well as low noise, broadband optical frequency combs with smooth spectral envelopes. Here we study the influence ...

Enhanced response in Brillouin distributed optical fibre sensors by simultaneous time and frequency pump multiplexing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Li Zhang

A technique to enhance the response of Brillouin distributed sensors is proposed and experimentally validated. The method consists in creating a multi-frequency pump pulse interacting with a multi-frequency continuous-wave probe. The power of each pulse at ...

Design of efficient single-stage chirped pulse difference frequency generation at 7 μm, driven by a dual wavelength Ti:sapphire laser

Christoph Peter Hauri

We present simulations for a design of a high-energy single-stage mid-IR difference frequency generation adapted to a two-color Ti:sapphire amplifier system. The optimized mixing process is based on chirped pulse difference frequency generation (CP-DFG), a ...

Sub-femtosecond precision measurement of relative X-ray arrival time for free-electron lasers

Christoph Bostedt, Christoph Peter Hauri

Today's brightest coherent X-ray sources, X-ray free-electron lasers, produce ultrafast X-ray pulses for which full-width at half-maximum durations as short as 3 fs have been measured(1). There has been a marked increase in the popularity of such short pul ...

Sum frequency and second harmonic generation from the surface of a liquid microjet

Sylvie Roke, Nikolay Smolentsev, Yixing Chen, Kailash Chandra Jena

The use of a liquid microjet as a possible source of interest for Second Harmonic Generation (SHG) and Sum Frequency Generation (SFG) spectroscopy is examined. We measured non-resonant SHG scattering patterns from the air/water interface of a microjet of p ...

Generation of broadband THz pulses in organic crystal OH1 at room temperature and 10 K

Christoph Peter Hauri

We studied the effects of cryogenic cooling of a 2-[ 3-(4hydroxystyryl)-5, 5-dimethylcyclohex-2-enylidene] malononitrile (OH1) crystal on the generation of broadband THz pulses via collinear optical rectification of 1350 nm femtosecond laser pulses. Coolin ...
