The Formation of Concentric Rings Induced by Defocusing Femtosecond Laser on Si Surface
We have observed the formation of the concentric rings on silicon surface induced by defocusing femtosecond laser. We develop a method to illustrate that the formation of such rings is attributed to the Fresnel diffraction.
