The Center of Advanced Laser Applications (CALA), a new high-intensity laser infrastructure, is nearing completion of commissioning its main laser system ATLAS-3000. The target parameters of the laser are 60J pulse energy in 25 fs at 1 Hz repetition rate. Currently, the laser pulses is serving experiments in two of CALA’s target area while its peak power is being ramped up in accordance with...

A well known means of increasing the cross section of fusion reactions and potential output energy gain is to use polarized particles [1]. For polarized fusion to occur, polarized and accelerated fuel is required. We have studied experimentally and theoretically the feasibility of laser-driven polarized ion acceleration using the PHELIX facility at GSI Darmstadt [2]. In our preparatory studies...

Experiments on the direct laser acceleration of electrons in long scale plasma of near critical density were carried out at the PHELIX laser facility at GSI, Darmstadt. Low density polymer foam layers of 300-450 um thickness and combination of foams with um up to mm-thin plane metallic foils were used as targets. Analysis of the electron energy distribution by application of the foam layers...

The importance of a high laser contrast in laser-plasma experiments is widely known. While the temporal contrast in the nanosecond time scale is well understood and optimized, short pulse laser systems around the world still suffer from a slow rising slope of the peak and hence a worse contrast in the regime of picoseconds prior the peak intensity.
We identified noise in a CPA stretcher to be...
