Non-contact sub-nanometer optical repositioning using femtosecond lasers

Optical components like resonator or waveguides often have stringent requirements in term of positioning accuracy during packaging. While this can be done routinely in a laboratory environment, permanently positioning and aligning optical elements with nan ...

Ultrafast laser ablation for targeted atherosclerotic plaque removal

Demetri Psaltis, Donald Benjaman Conkey, Thomas Jean Victor Marie Lanvin, Laurent Descloux

Coronary artery disease, the main cause of heart disease, develops as immune cells and lipids accumulate into plaques within the coronary arterial wall. As a plaque grows, the tissue layer (fibrous cap) separating it from the blood flow becomes thinner and ...

Differential chirped-pulse pair for sub-meter spatial resolution Brillouin distributed fiber sensing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang

A distributed fiber sensor based on a differential chirped-pulse pair Brillouin optical time domain analysis (DCPBOTDA) is proposed for sub-meter spatial resolution sensing. The technique is based on the subtraction of two measurements made with the same p ...

Femtosecond resolution timing jitter correction on a TW scale Ti:sapphire laser system for FEL pump-probe experiments

Christoph Peter Hauri

Intense ultrashort pulse lasers are used for fs resolution pumpprobe experiments more and more at large scale facilities, such as free electron lasers (FEL). Measurement of the arrival time of the laser pulses and stabilization to the machine or other sub- ...

Laser-assisted morphing of complex three dimensional objects

Yves Bellouard, Jakub Drs

Morphing refers to the smooth transition from a specific shape into another one, in which the initial and final shapes can be significantly different. A typical illustration is to turn a cube into a sphere by continuous change of shape curvatures. Here, we ...

Photonic chip-based optical frequency comb using soliton Cherenkov radiation

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Martin Hubert Peter Pfeiffer, Tobias Herr

Optical solitons are propagating pulses of light that retain their shape because nonlinearity and dispersion balance each other. In the presence of higher-order dispersion, optical solitons can emit dispersive waves via the process of soliton Cherenkov rad ...

Generation of 1.5-octave intense infrared pulses by nonlinear interactions in DAST crystal

Christoph Peter Hauri

Infrared pulses with large spectral width extending from 1.2 to 3.4 μm are generated in the organic crystal DAST (4-N, N-dimethylamino-4′-N′-methylstilbazolium tosylate). The input pulse has a central wavelength of 1.5 μm and 65 fs duration. With 2.8 mJ in ...

Temporally resolved second-order photon correlations of exciton-polariton Bose-Einstein condensate formation

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Mitchell David Anderson, Hadis Abbaspour, Albert Adiyatullin

Second-order time correlation measurements with a temporal resolution better than 3 ps were performed on a CdTe microcavity where spontaneous Bose-Einstein condensation is observed. After the laser pulse, the nonresonantly excited thermal polariton populat ...

Monolithic transparent 3D dielectrophoretic micro-actuator fabricated by femtosecond laser

Yves Bellouard, Tao Yang

We demonstrate a three-dimensional (3D) monolithic micro-actuator fabricated by non-ablative femtosecond laser micromachining and subsequent chemical etching. The actuating principle is based on dielectrophoresis. An analytical modeling of this actuation s ...
