Reidispongiolide A and B, two new potent cytotoxic macrolides from the New Caledonian spongeReidispongia coerulea

Two new 26-membered macrolides, reidispongiolide A (I) and B (II), were isolated from the New Caledonian marine sponge R. coerulea and their structures elucidated. They are related to sphinxolides previously isolated from an unknown nudibranch and later from the sponge Neosiphonia superstes. I and II co-occur with sphinxolide B and D. These macrolides exhibited potent cytotoxicity against various human carcinoma cells

VISAR diagnostic at LIL facility

A Velocity Interferometer for Any Reflector (VISAR) [1, 2] and a Streaked Optical Pyrometer (SOP) [3] were implemented on the “Ligne integration Laser” (LIL) facility. Spatial resolution as good as 10  μm in the target plane and velocity resolution as good as 0.1 km/s can be achieved. Several campaigns were performed in 2010 involving various experimental setups and physical processes: Boron EOS, Pre-compress H2 with special setup of diamond anvil cell and Shock coalescence. This feedback will be of a great help for the Laser Mégajoule facility (LMJ) VISAR design

Femtosecond Lidar and Coherent Control

We present the most powerful white light femtosecond Lidar experiment to date using a 30J-30TW laser. We also discuss the applicability of coherent control to femtosecond Lidar experiments, in order to identify bioagents in air

32 TW atmospheric white-light laser

Ultrahigh power laser pulses delivered by the Alisé beamline (26J, 32TW pulses) have been sent vertically into the atmosphere. The highly nonlinear propagation of the beam in the air gives rise to more than 400 self-guided filaments. This extremely powerful bundle of laser filaments generates a supercontinuum propagating up to the stratosphere, beyond 20km. This constitutes the highest power “atmospheric white-light laser” to date
