With a laser pulse, more efficient bulbs

It can be achieved that a 60 watt incandescent bulb emits the same light as a 100 watt bulb emitting the laser pulses of a tungsten femtosecond filament. This has been achieved by researchers at Rochester University in New York State. It is explained that the laser rays are able to melt the metal with its heat, but if the duration of the laser pulse is very small, the metal molecules are only rearranged without getting to melt. With the new molecular arrangement, tungsten provides much more light without consuming more electricity. In some ways, tungsten is tanned and increases its ability to receive and emit radiation.
