Laser is light amplification by stimulated emission of radiation. Fresnel lens doesn't amplify light it focuses it. It is not stimulated, it is just passive component.

This is true, but I don't think many people think of laser as anything other than "dangerous light." That's how I used it. Colloquial meanings can be frustrating when they clash with the technical meaning, but trying to fight them is typically futile.

>> "2 : something resembling a laser beam in accuracy, speed, or intensity "

I gave up on fighting "CPU means the entire computer" a long time ago.

"Many people" have taken first year physics, or at least read a wikipedia article, and understand that the defining feature of a laser is its coherence.

But, sure. It's 2020. We live in a post-factual society, words have no meaning and it's impossible to know anything. Why resist?
