    More amazing news : Solid state masers operating at room temperature are coming to a place near you soon !

    The side effect that is interesting :
    "
    Conventional MASER technology using hard inorganic crystals such as ruby, only works when the ruby is kept at a very low temperature. The team in today's study have discovered that a completely different type of crystal, namely p-terphenyl doped with pentacene, can replace ruby and replicate the same masing process at room temperature.
    As a curious twist, the pentacene dopant turns the otherwise colourless p-terphenyl crystal an intense reddish pink – making it look just like ruby!

    awesome!

    does this mean we might actually get $20 disc burners that hold terabytes without being prone to dataloss?

    what does this mean actually? what could we do with cheap microwave lasers? can i hook them to a wall socket and turn it into a phaser?

    ^^ No. But we can make cool weapons that boil people/plants from far. And a tin foil hat will be a good shield to protect your brain :p

    microwaves are the wrong direction.
    microwaves - InfraRed - Visible - Ultra Violet - X-ray

    we used to be making cd burners with red light visible light, then came dvd burners with orange visible light, blu ray players use blu visible light.

    The next optical storage would move towards ultra violet and x-ray, not microwave.

    One step closer to Laser swords :p

    Right now masers are used to communicate with satellites. For example, the Voyager spacecraft is some 10 billion miles away and can get away with using a 23 watt radio to send messages back to earth because we have giant dish antennas powerful enough to detect a signal weaker than a snowflake hitting the ground. The problem is sending a signal back to Voyager which has a much smaller antenna and not nearly as much power to amplify signals. A conventional microwave signal broadcast would spread out in all directions and require enormous power to cover the distance and still be picked up. A maser is like a laser and the beam doesn't spread nearly as much and a lot less power can be used to contact Voyager.

    Theoretically such a room temperature maser could be useful for cellphone towers, any satellite in orbit, or any line of sight microwave communications requiring a lot of power. Not sure how useful it would be as a weapon or for much else, but I'm sure people will figure out other uses if it becomes cheap. However, this first one is a very crude prototype that isn't good for much and designing these kinds of things can be as much an art as a science. Something the British have been famous for though since they invented radar in WWII.

    i bet you could make the perfect soldering iron. heat the solder from the inside first. also, i bet nathan myrvold will figure out a way to cook with it-can you imagine tiger striped filet mignon that is rare with pencil thin stripes of pink?

    i would worry about the brain thing though- it will certainly contribute to our stupidification - some company will put it into the next smartphone, tell us it's safe and we'll slowly cook our temporal lobes.
