Now, in continuation to the word “fast,” scientist have their own versions. GHz of speeds is perhaps eternity for us, but those sitting in the labs just need reasons to expand. Reason enough is more computing speed, and to the rescue is “saser,” a beam of photons developed by scientists at the University of Nottingham, which intends to take the modest computing speeds to as fast as a terahertz, and that’s about a 1000GHz. Warp speed isn’t possible, but that’s even faster in computing, I guess.
Saser, the beam of sound waves on a nanoscale, is a sonic equivalent to the laser, which instead of taking the optical cavity (the laser beam passage) travels through a manmade structure called a superlattice. On generation of light for power, the beam of photons increase in number and gushes out of the structure is form of ultra-high frequencies.
With a potential to transform the area of acoustics, the sasers can have multiple applications, given the possibility to detect and emit sound waves in mesmerizingly high terahertz frequency ranges.
