Données paléomagnétiques du bassin permien de Rodez et rotations dans la bordure sud-ouest du Massif central

Abstract: The palaeomagnetic study of the Rodez Permian basin yields two poles for the formations attributed to the Thuringian: 48.0 °N, 166.1 °E, K = 453, A95 = 2.7 ° and 52.4 °N, 165.9 °E, K = 68, A95 = 3.9 °. Comparison of these new data with those previously acquired in the neighbouring Permian basins shows that the post-Saxonian rotation already known in the Saint-Affrique basin very likely affected also the Rodez and Brive basins.

8xx - 10xx nm highly efficient single emitter pumps

Abstract: Higher reliability and power efficiency achieved with low-demanding cooling make single emitter diodes a more effective pump source than monolithic laser diode arrays. Continuously improving performance and increasing brightness of single emitter pumps are accompanied with a steady reduction of cost of pumping (dollar-per-watt). Performance advantages do not compromise reliability of the pumps. These features ensure that single emitter diodes are the most effective solution even for multi-kWatt systems pumping. Here we report on a recent progress in single-mode and multi-mode edge-emitting diodes.

High-power 780-nm single-frequency linearly polarized laser

Abstract: In this work we represent a highly efficient (>20%) CW second harmonic generation in PPKTP and PPLN crystals As a fundamental source we used a high power (>24W) single-frequency ( 20% for PPLN and >7% for PPKTP was demonstrated We also demonstrate a possibility of single mode fiber delivery for this SHG source with excellent beam quality (M2 <11) Pump power dependency of conversion efficiency and other SHG characteristics for PPLN and PPKTP would be presented and compared

Permanence des flux de masse d'une rivière en tresses expérimentales

Abstract: A small-scale experimental braided river system has been reproduced. This experiment shows that: (i) destabilisation of the river occurs through sediment feeding; (ii) for constant input fluxes of mass, transfer by the river evolves towards a steady state in which mass fluxes at each end of the reach remain constant although instable braiding remains inside the box; (iii) instability of the braided river remains both when the system aggrades or degrades.
