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。

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

但是将这种推力转化为一种拉力需要更加复杂的光学，比如，在格里尔的设计中，是通过一种螺线管状光束。

But turning this push into a pull required more sophisticated optics -in Grier's case, a solenoid beam.
