Fundamentals do not replace reality. They accelerate access to it.
A system is more than its components. How source, optics, motion, and software interact determines what the process can deliver.
Production conditions are the final judge. What works in the lab may fail on the factory floor — and vice versa.
Stability is a state, not a permanent one. Machines age and wear. Environmental conditions influence the process whether you control them or not. The question is whether you see it before your parts do.
This model holds — across nearly two decades, five industries, every laser type from CW to femtosecond, and wavelengths from 193 nm to 10.6 µm. A laser system is only as good as the understanding of how process, system, and environment interact. Over time.
