Dr Tanaka used a pulse of laser light.
ECONOMIST: This year, the Nobel authorities have shown a deft touch
In mid-December, the company was granted a new U.S. patent protecting key areas related to its laser pulse technology.
It operates by focusing a laser pulse in the air to create a high energy plasma ball (up to several kilometers away) at a target.

For the camera, a laser pulse is fired at a wall, and the impact of hitting the wall causes the particles of light to scatter.
It has also scanned the surface of the planet using Mola (Mars Orbiter Laser Altimeter), which beams an infrared laser pulse towards the surface of the Red Planet 10 times a second.
The fast-ignition technique is more like a petrol engine: first the fuel is compressed and only then is it ignited by a second laser pulse acting as a spark plug that is fired through a hole in the pellet.
Once that is done, another laser pulse will jostle the virus from its ground state into an excited state, just as a single atom is excited by moving one of its electrons from a lower to a higher orbital.
We call this new imaging technology femto photography because we capture a segment of the image with a flashlight (in this case, a laser pulse) on for a few millionths of a billionth of a second (or a few femtoseconds) and an exposure time approaching a trillionth of a second.
Once the "messenger" group had merged with the second cloud, a second laser was shone through the condensate to revive the original pulse of light.

According to Andy Mazzara, the director of the Institute for Non-Lethal Defence Technologies at Pennsylvania State University, prototypes of such devices use a laser to create an ionised channel of air through which an electromagnetic pulse is directed.
That means that although the laser's electrical input is about the amount needed to run a bedside lamp, an individual pulse has an intensity of several million watts.
