The beam itself will be produced by a device called a fibre laser.
激光波束本身将由光纤激光设备产生并在一个细长的光纤核心产生激光束的相干光。
This generates the coherent light of a laser beam in the core of a long, thin optical fibre.That means the beam produced is of higher quality than other lasers, is extremely straight
这意味着产生的激光波比其它激光有更好的品质,并且直线度极高。
and can thus be focused onto a small area.
这样就能将能量集中传送到一个小的区域范围内。
Another bonus is that such lasers are becoming more efficient and ever more powerful.
这种激光波的另一个优点是具有更高的效率和更强的能量。
In the case of Dr Sweeney s fibre laser, the beam will have a wavelength of 1.5 microns,making it part of the infra-red spectrum.
以斯威尼博士研发的光纤激光器为例,它产生的激光波束波长为1.5微米,这使其成为红外线光谱的一部分。
This wavelength corresponds to one of the best windows in the atmosphere.
此波长对应于大气中的最佳窗口之一。
The beam will be aimed at a collector on the other side of the hangar, rather than severalkilometres away.
