Self-organizing structures of nanometer size are observed on the surface of crystalline irradiated by strongly absorbed Nd:YAG laser radiation (LR) at intensities within 4 - 12 MW/cm2. The effect of exciton quantum confinement manifested by a shift to higher ener-gies of the A0,X exciton line of the photo-luminescent spectrum is present in structures of 10 – 15 nm in diameter at the top of nano-hills. A graded band gap structure with optical window develops at the top of nano-hills
