摘要
Intense XUV and soft X-ray emission from laser-produced plasma sources are currently of great interest for a variety of research applications including inertial confinement fusion, and X-ray backlighting. Optimization of X-ray lines such as the He-alpha line (resonance line 1S2P P-1(1)-1S(2) S-1(0)), the inter-combination line (1S2P P-3(1) - 1S(2) S-1(0)), the di-electronic satellite (1S2P(2) D-2 - 1S(2)2P P-2) lines and the K-alpha lines along with bremsstrahlung radiation in the spectral range 0.8-8.5 key has been carried out using a 20 J/500 ps laser system. Optimization has been performed by changing the laser energy at fixed laser focal position and with focal position variation while keeping the laser energy constant. (C) 2013 Elsevier B.V.
