Optofluidic evanescent dye laser based on a distributed feedback circular grating

Demetri Psaltis, Wuzhou Song, Andreas Vasdekis

We demonstrate an optofluidic evanescent laser based on a solid circular distributed feedback grating with the dye solution acting as the cladding layer. The laser mode is confined within the grating and experiences optical gain via the interaction between ...

Sub-ppm multi-gas photoacoustic sensor

Luc Thévenaz, Jean-Philippe Besson

A photoacoustic multi-gas sensor using tuneable laser diodes in the near-infrared region is reported. An optimized resonant configuration based on an acoustic longitudinal mode is described. Automatic tracking of the acoustic resonance frequency using a pi ...

Simultaneous Multicolor Fluorescence Cross-Correlation Spectroscopy to Detect Higher Order Molecular Interactions Using Single Wavelength Laser Excitation

Theo Lasser

Fluorescence cross-correlation spectroscopy is a powerful method for the study of molecular interactions and dynamics in solution and even in living cells. Usually, in the optical setup, either two laser beams have to be superimposed in their respective co ...

Efficient Stimulated Raman Pumping for Quantum-State Resolved Surface Reactivity Measurements

Thomas Rizzo, Rainer Beck, Plinio Maroni

We describe the use of stimulated Raman pumping in a molecular beam to perform quantum state resolved gas-surface reactivity measurements for molecules prepared in totally symmetric vibrational states. Vibrational states of homonuclear diatomics as well as ...

Cristal composite SLAB pompé latéralement par diodes laser

Simon Benjamin

This work presents the development of an original concept of a side pumped diode pumped crystal laser for the generation of a high power near diffraction limited beam for material processing applications such as cutting, marking and drilling. An approach b ...
