    Excerpt:

    The reign of Queen Victoria saw a number of advancements in technology: steam engines, the beginnings of the electrical industry, and, of course, the introduction of lasers into mainstream life. French Scientific pioneers such as Prof. Fermé D’Aperture and Dr. Flickre Galveaux led the development of the first coal-gas lasers, using bituminous vapors as lasing media...

    ... yes, absolutely! -- there's a real chance, that Leaonardo da Vinci had some related or path-breaking ideas and development too

    It is my understanding that it would only work with certain types of coal. It was later found that it was the copper in the coal that lased and the uranium decay giving off helium3. Some minor lines in the uv were there from nitrogen but they didn’t have tech to see those lines at the time. Sometimes they got more lines because of selenium.

    The shame was the runtime was short due to fouling of the Tolkien mirrors (an all stop filter- non shall pass)by tar pitch. They were able overcomethe issue to some extent by using a rotating window that left the chamber and was clean in solvent and the squeezed dry as it re entered the chamber. Unfortunately they used a chlorinated relative of methylene chloride that had a residual HF component that etched the glass.
