Some Japanese researchers managed to create real aerial interactive holograms using femtosecond lasers. What are the chances that this technology could be used to create a complete functional Holodeck like that seen in Star Trek?
Cant click the link now but isnt this old as fuck? Like at least a year or two. Id say unlikely for a holodeck experience, but give it a few decades and we might see some practical uses in telecommunication
Are you talking about this?
That's Burton Aerial which was announced in 2011 iirc and it's literally obsolete. This Fairy Lights was announced half a year ago, uses femtosecond lasers and can generate high resolution pictures in a volume of 5 cm^3, the principle is the same but the laser used is more safe (this kind of laser is the same used for eye surgeries by the way).
The main difference between Burton Aerial and Fairy Lights is that the latter was designed to be safer and with physical interaction as focus point, the laser pulse is weaker and much shorter (10^15 pulses per second), that's why the guy in the video is able to touch it with his bare finger.
Is ozone that dangerous to begin with? the ozonosphere is thinning, I doubt a little ozone generated by these things will unbalance the atmosphere.
Maybe with liquids, projecting the lasers inside a translucent container filled with some chemical or something like that, in the video they show that the laser can generate green and read when projected through a certain glass (refraction I guess), though I didn't read the details yet.
