← ScienceWhich outcome occurs when machining steel using laser interference lithography?
A)Precise surface nanostructure formation occurs✓
B)Uniform melting of the steel ensues
C)Ablation ceases due plasma formation
D)Laser power gets totally absorbed
💡 Explanation
Using laser interference lithography for machining steel causes precise nanostructure formation because constructive and destructive interference patterns create areas of high and low energy deposition respectively. Therefore, localized ablation results rather than uniform melting or full absorption.
