N2 - K-shell x-ray spectroscopy of sub-100 nm Al foils irradiated by high contrast, spatially uniform, 150 fs, [Formula presented], laser pulses is obtained with 500 fs time resolution. Two distinct phases occur: At [Formula presented] a broad feature comparable to the resonance transitions occurs due to satellites, and at [Formula presented] the resonance transitions dominate. Initial satellites arise from a large area, high density, low temperature ([Formula presented]) plasma created by fast electrons. Thus, contrary to predictions, a short, high intensity laser incident on a thin foil does not create a uniform, hot dense plasma.
