The new laser allows you to print on T-shirts smartphones

According to a new report, published in the journal ACS Nano, a team of Australian engineers modeled the type of laser called Spaser, which in the future can create electronics and smart phones in particular, are so tiny and flexible that they can be printed on a T-even.

Simply put, Spacer is a nanoscale laser, emitting a beam of light through the vibration of the free electrons in contrast to the relatively cumbersome conventional laser beam. New Spacer, described in the report, will be made of carbon fiber.


"Other lasers, based on the same technology, are made of semiconductor nanoparticles and quantum dots made ​​of gold or silver, whereas our device would consist of a cavity made ​​of graphite and strengthening elements, made ​​of carbon nanotubes. Use of carbon means that our Spaser is more reliable and flexible, and is capable of operating at high temperatures and be environmentally friendly. Because of these properties in the future, for example, can be printed slim mobile phone even on clothes, "- said study author Chanaka Rupasinghe, a graduate student at Monash University in Australia.

New technology is capable, according to the researchers, to replace the existing transistor components, which are made on the basis of modern microprocessors, memory, displays and other electronics. Devices such as Spaser, help to overcome the current limitations of miniaturization and bandwidth. The scientists said their Spaser will be built using graphene and carbon nanotubes, which are more than a hundred times harder than steel and have excellent conductivity. They can also withstand much higher temperatures.  

The study showed that graphene and carbon nanotubes may interact with each other and to transport energy through light. These optical relations are very fast and energy efficient, making them suitable for use in computer processors, as well as for other purposes.
