Notes:
Kα emission is observed from the interaction of a picosecond, 1.05 μm laser pulse at 4×1015 W/cm2 with a silicon target coated with various thicknesses of aluminum. Strong Kα emission requires a p-polarized, high-intensity-contrast laser pulse. At 7.1 A(ring), the Kα yield is 1.5×108 photons/sr with a duration of emission of ≤8 ps and a source area of 1.6×10−6 cm2. The radiance is ≥3×109 W/cm2 sr. Monte Carlo simulations have suggested that under these conditions Kα emission is a promising candidate for an efficient, ultra-short-duration x-ray source at ∼1.5 A(ring).
