One successful laser setting does not define a process window. Design a blocked, randomized, replicated experiment that preserves delivered beam and formulation state, separates coupled factors, measures useful response and damage together, models interactions and uncertainty, and confirms a feasible region across parts, fields, lots, and tools.
