The electronic structure of phosphorus is essential to the understanding of the laser-induced damage of potassium dihydrogen phosphate (KDP) crystals. The surface electronic structure of retired components and KDP crystals irradiated with different fluences are studied by X-ray absorption near-edge structure. Results indicate that the A/C ratios (the peaks A and C corresponding to the electron transition from 2p→3s and 2p→3p, respectively) in the L2,3-edge spectra are up to 0.9 for the retired samples, and the damage is inhomogeneous on the surface. Furthermore, the electronic structure of phosphorus is associated with laser induced damage.
