This crazy laser can stop lightning

Yes please. Like do what is the difference between a laser diode, an LED, halogen, etc. Car headlights have all of those, and then wattage, cooling, optical efficient, photons and wavelengths vs energy levels. Some excite gases with electricity, some use solid materials to make different colours. We even had a Nobel prize for a blue LED I think. That's a good part of the story and why is tech always had non-blue LEDs, so now they seem more expensive. I know a bunch about this stuff but never put it together. Would be a super cool video. Most people do not understand how different types of lighting, and especially lasers, work. I mean, we even use them to create fusion!
