Abstract:
The interaction between multiple intense ultrashort laser pulses and solids typically produces a regular nanoscale surface corrugation. A coupled mechanism has been identified that operates in a specific range of fluences in GaAs that exhibits transient loss of the imaginary part of the dielectric function and X2, which produces a unique corrugation known as high spatial frequency laser induced periodic surface structures (HSFL). This mechanism is unique in that the corrugation does not involve melting or ablation.

Claim (Index 1):
A method of manufacturing a surface corrugation in a material using light energy, said method comprising:\n applying a plurality of laser energy pulses at the material, each of said plurality of laser energy pulses being about 150 femtoseconds in duration, said plurality of laser energy inducing point defect accumulation and diffusion in the material resulting in surface corrugation, the surface corrugation having a period less than 0.3 times a wavelength of the laser.
