A new static Fourier-transform spectrometer: The first spectra from Synthesis Temporal Aperture Reconstruction spectrometer

Autor: Laurent Sarger, Bruno Bousquet, Stéphane Santran, Lionel Canioni, Patrice Nagtegaele

Publikováno v: Fourier Transform Spectroscopy/ Hyperspectral Imaging and Sounding of the Environment.

In the framework of spatial aperture synthesis, we developed a temporal aperture synthesis allowing the concatenation of several interferograms. We succeed to enhance the resolving power of static Fourier-transform spectrometers by a factor of 40.

Moment-based description for assumption-free single-shot measurement of femtosecond laser pulse parameters via two-photon-induced photocurrents

2006 Northern Optics Conference Proceedings, Jun 2006, Bergen, Norway. pp.67-+, ⟨10.1109/no.2006.348376⟩

By examining the first- and second-order moments of intensity with respect to time and frequency, we arrive at a temporal characterization of laser pulses through parameters for pulse duration, group delay dispersion and temporal form. These paramete

Nonlinear refractive index of photo-thermo-refractive glass

Autor: M.E. Martinez-Rosas, Larissa Glebova, Alan Tirpak, Leonid B. Glebov, Lionel Canioni, Stéphane Santran, Laurent Sarger

Publikováno v: Optical Materials
Optical Materials, Elsevier, 2006, 28 (4), pp.401-407. ⟨10.1016/j.optmat.2005.02.004⟩

Nonlinear properties of a photo-thermo-refractive (PTR) glass are studied and compared with those in fused silica and a conventional optical glass. PTR glass is a new photosensitive medium for high-efficiency phase volume hologram recording which man

Publikováno v: Journal of the Optical Society of America B
Journal of the Optical Society of America B, Optical Society of America, 2004, 21 (12), pp.2180-2190

We present precise and absolute measurements of full complex third-order optical susceptibility on different fused-silica and original glasses composed of tellurium, titanium, and niobium erbium. These materials are designed to be the key point for a

Characterization of optical nonlinearity in semiconductor photodiodes using cross-polarized autocorrelation

Autor: Stéphane Santran, M.E. Martinez-Rosas, Laurent Sarger, Lionel Canioni

We study the various nonlinear effects produced during the detection of high-intensity signals in semiconductor photodiodes. Experimental results on few commercial detectors are compared with theoretical analysis. This analysis is based on the tensor
