Crystalline Flat Surface Recovered by High-Temperature Annealing after Laser Ablation

Crystalline Flat Surface Recovered by High-Temperature Annealing after Laser Ablation

Ultra-short laser pulses (1030 nm/230 fs) were used to laser ablate the surface of crystalline sapphire (Al<sub>2</sub>O<sub>3</sub>) at high intensity per pulse 20–200 TW/cm<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inli...
