Just read the article and didn't see anything about building an actual laser… what details the article has (and its scant) its seems they took a fluorescing layer and sandwiched with a color wheel and added the additional wiring and control circuitry… (Obviously more nuanced and interesting physics but still…) cool and practical, but not a diode and definitely not a laser… I could be wrong and would love to be!

… now, if that setup could be drawn out into a fiber laser as cladding with a wide spectrum neural amplifying core (if such a material exists) that could maybe be something idk
