Collisionless shock acceleration of protons and C^{6+} ions has been achieved by the interaction of a 10^{20} W/cm^{2}, 1 μm laser with a near-critical density plasma. Ablation of the initially solid density target by a secondary laser allows for sy

The design of narrow-band Compton scattering sources for specific applications using nuclear resonance fluorescence (NRF) is presented. NRF lines are extremely narrow (ΔE/E∼10^{-6}) and require spectrally narrow sources to be excited selectively a
