What i was wondering…exactly… how do you make this kind of a laser? And imagine an xray laser… you could fry the guidance system of drone very precisely

- was_a_dev 2y agoHere, it appears they have used Four Wave Mixing in Xeon gas https://en.wikipedia.org/wiki/Four-wave_mixing https://en.wikipedia.org/wiki/Four-wave_mixing
- drakebake 2y agoOne has to first imagine that a photon isn't as immutable as one sometimes believes. Effectively by putting lots of photons together in a medium (the medium makes sure momentum and energy is conserved) one can create all kinds of colors of light. We can already make "lasers" up to x-rays in synchrotrons by using the right means. The definition of laser becomes a bit shady though as the light is coherent and has a small divergence angle, but is not produced through stimulated emission.
