Default Sound lasers inch closer to reality

I found a nice article about Sound Lasers some time ago, does anyone heard or know more about this

Sound lasers inch closer to reality-sound_laser-1.jpg

Fifty years after the invention of the optical laser, two separate research groups have independently made important steps toward making phonon lasers - a type of laser that emits very high-frequency, coordinated sound rather than light waves - a reality. The studies, published in the current issue of the journal Physical Review Letters, could lead to a completely new kind of laser that could find interesting applications in medical imaging.

The quantum nature of light means its' possible to emit coherent photons of the same frequency and phase, in a process called "stimulated emission". This was predicted in 1917 by Albert Einstein and first put into practice in 1960, when the first optical laser was built.

Despite some fundamental differences, light and sound waves are both formed by quanta, meaning that sound lasers (or "sasers") are also possible. Researchers have been looking at sound lasers for some time, but haven't been able to build one working at very high (terahertz) frequencies just yet.

The interest around sound lasers is not just purely academic: sound propagates at a speed that is about 100,000 smaller than the speed of light, and therefore has a proportionately smaller wavelength, along with lower energy levels. The combination of these two factors means sound lasers would allow for extremely precise imaging of living tissue without damaging it in the process (as is often the case with optical imaging).

The main obstacle to the implementation of a high-frequency saser is also what makes it so attractive: the shorter wavelengths make it harder to coordinate the quantum particles to travel coherently and realize the "stimulated emission" in phonons.

Two research teams from the US and the UK tackled the problem using different approaches, and both made important progress towards making sasers a reality. A group from Caltech assembled a pair of microscopic cavities that only permit specific frequencies of phonons to be emitted, effectively producing a resonator that ensures the waves are always in phase with each other.

A second group from the University of Nottingham in the UK took a different approach: they built their device out of electrons moving through a series of structures known as "quantum wells": whenever an electron hops from one quantum well to the next, it produces a phonon. While this system doesn't have the properties of a true phonon lasing, the system showed it amplifies high-frequency sound and could be used in the future as a fundamental building block of the first sound laser.

Both these studies are important breakthroughs that will one day bring to practical, high-frequency phonon lasers. While it's hard to predict right away what repercussion this could have in the long run the optical laser was deemed next to useless shortly after being invented medical imaging would surely benefit greatly from its development even in the short term.

When I was a kid --- I read an article about an acoustic laser made by the army. It had 16 low freq transducers mounted on a board and as I recall, it busted up a concrete wall. That's 45 years ago and I don't recall much more. They also had a picture of a plate with a bunch of tuned whistles which was also being tested.

Default Re: Sound lasers inch closer to reality

I remember attending a seminar where they were talking about patents and stuff, and as a demonstration of some "neat ideas" he had this speaker that could send out a beam of sound wherever he pointed it. It wasn't a parabolic dish or something like that either, but this flat surface that made the sound, and you could only hear it if he pointed it at you. It was pretty cool.

Now terahertz frequencies... that's a different story.

@Bionic-Badger: About a month or so ago, I watched a show called 'Conspiracy Theory' with host Jesse Ventura. Anyway, if memory serves me correctly, they interviewed a man that created spy devices and such, and he showcased almost the exact same device you mentioned. He pointed the device at Jesse Ventura, and only Jesse could hear the sounds.

Cracking Aircraft Windows with Directed Sound Waves

Today our modern military scientists have found many uses for directed energy beams. Some of these uses include communication, non-lethal weapons and high-energy lasers. Directed sound waves and harmonics maybe the answer to stopping manned aircraft in the battlespace on its way to find our blue force as its next target. Using such directed waves we can penetrate and crack aircraft canopies, rendering the aircraft useless to continue the mission. Or so disrupt the enemies mission that it is forced to turn back completely and abort or even force the enemy pilot to eject immediately.

Currently we have talking glass technologies, which vibrate windows and can be used to whisper sounds. These same technologies, which are currently produced with acoustic transducers attached to the windows can also be replicated from a distance with directed sound. Since glass, Plexiglas etc are brittle a certain type of vibration will cause them to crack and thus a breach in the aircraft at altitudes above a certain height become immediate problems for the pilot, taking precedence over mission and going to the heart of a human's need for self preservation.

Recently a Delta Airlines flight had to make an emergency landing after the airplane's windshield cracked. Often flights with breaches in the pressurization system are forced to land or fly below twelve thousand five hundred feet where the oxygen percentages in the air are livable for humans. When even a crack appears pilots must take action as the concerns of loss of cabin pressure take priority.

A weapon of this type, which can crack windshields of aircraft would deter manned aircraft from entering a safety zone containing our military or civilian assets. Such a weapon would be inexpensive to use and save millions of dollars in anti-aircraft missiles, which often fail to hit their mark when the enemy has sufficient counter measures.

Default Re: Sound lasers inch closer to reality

interesting notes there (pardon the bad pun). I suspect however directed sound weapons vs aircraft would lose efficiency once the aircraft is traveling at about mach 1. Requiring the use of such weapons from forward of it's direction of travel. Very much wouldn't be able to replace anti-aircraft missiles, however it might be a nice first line of defense. I wonder what effectiveness a weapon based on this tech would have when aimed at the front of a supersonic aircraft, as it's not just sound in general that is required to break a glass, you also need specific frequencies for a given piece of glass. A jet moving at high speed towards the sound cannon would blue-shift the sound a bit. Might make it less effective even from the front. Either way, still potentially a first line of defense.

Actually, the maser preceded the laser by a few years. In fact, the original meaning of "Phaser" in Star Trek TOS was "PHotonic Maser" which is sort of redundant and, of course...a laser. They were being all science-fictiony, because nobody had ever heard of the laser. They changed it. Now it stands for PHASEd Energy Rectification, which is...still a laser.

Heh. Saser. Makes you wonder what else you could potentially - eh - "ase". Would subatomic particles work? A Naser? Paser? I guess an electron beam is a type of -aser. It's phased and can be focused and collimated..
