Unlike traditional lasers, which are bright in the middle and dimmer at the edges, a solenoid beam contains a bright spiral of intense energy.

传统激光束中间部分明亮而边缘部分较暗，而螺线管状光束则是一个高能量的明亮螺旋。

Scientific American magazine says huge lasers turn only about twenty to thirty percent of the energy they use into a laser beam.

It uses lasers to beam power from one place to another, but it too faces regulatory difficulties.

ECONOMIST: Wireless charging

That means the beam produced is of higher quality than other lasers, is extremely straight (even by the exacting standards of a normal laser beam) and can thus be focused onto a small area.

ECONOMIST: Solar power from space

If we used a bank of high-powered lasers, we could beam a high-bandwidth message across the cosmos.
