2017 42nd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
Transient-type stimulated emission in the terahertz frequency range has been achieved from silicon crystals doped by phosphorus and bismuth donors under optical excitation by a few picosecond-long pulses generated by the infrared free electron lasers

In this paper, we will employ two microscopy techniques, transmission electron microscopy and infrared nanospectromicroscopy, to study the production of polyhydroxybutyrate in Rhodobacter capsulatus and to evaluate the influence of glucose and aceton

We have studied the electron beam transverse adaptation in an FEL oscillator in a very large interval of wavelength (3 to 150 μm) and electron energy range (12 to 45 MeV). Beam dimensions are measured by a moving wire whose temperature dependent res

An X-ray Compton source is under development at the ELSA facility. The electron beam coming from the ELSA linear accelerator interacts with a laser beam to generate an X-ray flux in the direction of the electron beam. With a 17 MeV electron beam and

A study of a Compton source for X-rays in the ELSA facility is in line with the RADIOTHOMX project (THALES Communication, Colombes, France). The goal of this project is to develop a compact device to deliver an intense flux of monochromatic X-rays fo

Dinuclear gold(III) clusters with a rhombic Au(2)O(2) core and 2,2'-bipyridyl ligands substituted in the 6-position (bipy(R)) are examined by tandem mass spectrometry. Electrospray ionization of the hexafluorophosphate salts affords the complexes [(b

We show that an infrared spectromicroscopy method based on a photo-thermal effect, is able to localize single viruses as well when they are isolated and when they are located inside the bacteria they have infected. In this latter case, although the t

In this paper, we analyze in detail a new method of infrared micro-spectroscopy, which aims at performing "chemical mapping" of various objects with sub-wavelength lateral resolution by using the infrared vibrational signature characterizing differen
