Title: Two-photon absorption of soft X-ray free electron laser radiation by graphite near the carbon K-absorption edge

Abstract

Here, we have examined the transmission of soft X-ray pulses from the FERMI free electron laser through carbon films of varying thickness, quantifying nonlinear effects of pulses above and below the carbon K-edge. At typical of soft X-ray free electron laser intensities, pulses exhibit linear absorption at photon energies above and below the K-edge, ~308 and ~260 eV, respectively; whereas two-photon absorption becomes significant slightly below the K-edge, ~284.2 eV. The measured two-photon absorption cross section at 284.18 eV (~6 × 10–48 cm4 s) is 7 orders of magnitude above what is expected from a simple theory based on hydrogen-like atoms – a result of resonance effects.

Fig. 1 Fig. 1: Experimental schematic. X-ray pulses from the FEL are focused and either intercepted by a sample or allowed to transmit, before being dispersed by a grating and imaged by a camera. This design permits a direct determination of transmission. Right: Linear, total electron yield, spectrum for a 500 nm graphitemore » sample. X-ray TPA measurements were conducted at 3 discrete photon energies show in the dashed lines. Inset: Schematic of the dominant processes observed in this work, two-photon absorption. While linear (one-photon) absorption is always present, the rate of two-photon absorption is particularly sensitive to the absorption edge and the nature of the excited state. Only the lowest energy studied here is a virtual state. I0(ω) and I(ω) represent the intensity of the input (INS) and transmitted beams (IS/INS), respectively.« less
