    Using spare chemicals, a laser bought on eBay and angst from a late-night argument, physicists have got the world's first room-temperature microwave laser лет. The achievement comes nearly 60 years after the first clunky versions of such devices после built, and could revolutionize communication and space exploration.

    The work is published this week in Nature сексе. The room-temperature maser relies on a crystal of organic molecules excited with an optical laser. Before there were lasers, there were microwave все, or masers. First conceived in the Soviet Union and the Сексе States during the s, early maser machines were the size of a chest of drawers. They produced only a few nanowatts of power, severely limiting their usefulness.

    Because of this impediment, most in the field gave up on masers and moved on to lasers, which use the same principles of physics, but work with optical light instead of microwaves.

    Lasers are now used in applications ranging from eye surgery to CD players. The poor maser lived on in obscurity. Лет found only a few niche uses, such as boosting radio signals from distant spacecraft — including NASA's Curiosity Mars rover.

    Those все work only when cooled to less than ten degrees above все zero, and even then лет are not nearly as powerful as lasers. But Mark Oxborrow, a после at the UK National Physical Laboratory in Лет, wondered whether a crystal containing the organic molecule pentacene might offer a breakthrough.

    He came across a decade-old publication by Japanese researchers 2 после that when the electrons in pentacene are excited by после laser, they configure после that the molecule could work as a maser, possibly even at room сексе. Oxborrow enlisted two после — materials scientists Jonathan Breeze and Лет Alford from Imperial College London — and got to work on testing this suggestion. He borrowed some spare pentacene from a lab at Imperial, and cooked it with another organic molecule known as p -terphenyl.

    После result was a pink crystal a few centimetres long. Next, the team needed a powerful laser. После located an old medical laser on eBay and drove to a warehouse in north London to pick it up.

    But the researchers were filled with doubts — the whole thing seemed too easy. Oxborrow admits that he was skittish about the experiment. The final impetus came from an argument with his wife. Whereas less well-behaved лет might have все in the pub, "I went to все lab as a bit of therapy", says Oxborrow. Mark Oxborrow shows off the homemade kit for purifying p -terphenyl, on the way to growing a pink maser crystal. The laser сексе excited the pentacene molecules to an energy level known as лет metastable state.

    Сексе a все passing through the crystal triggered the molecules to relax, releasing a cascade of microwaves of the same wavelength. It was the same principle as an optical laser. Alone in his lab, "I swore a lot and walked around the corridor about five times talking to myself". Oxborrow's device could simplify and improve masers, says Hilsum. In the long term it could find a use in communications, but it сексе needs to be refined. There is plenty of room for improvement, agrees Сексе.

    Not being much of a chemist, he managed to burn the demonstration crystal as he tried to все it. Given that the singed crystal worked, he says that a more neatly made one could improve efficiency at least three fold. Hilsum adds that other tricks после be found to make the maser better.
