Hard x-ray generation by low energy, tightly focused laser pulses
The interaction of λ 2 laser pulses with plasma is studied to scale the high-field physics from high power laser systems to low-energy, high-repetition-rate lasers. For this purpose, 20 mJ , 40 fs Ti:sapphire laser pulses were focused in a spot of 2.2 × 2.3 μ m 2 with a maximum intensity of I ∼ 10 1...
