激光器不能远离发动机，因为他们的强光束会破坏任何光纤，这些光纤是用来将光传送到汽缸中的。
Nor could they be located away from the engine, because their powerful beams would destroy any optical fibres that delivered light to the cylinders.
另一种通讯方法可能是使用诸如现在为核聚变反应堆开发的那些非常强大的脉冲激光器。
Another method of communication could be through the use of incredibly powerful pulsed lasers, such as those now being developed for nuclear fusion reactors.
激光器不能先停下来，然后从停下来的地方重新开始，所以任何中断都是致命的。
The laser is not capable of stopping and then picking up where it left off, so any interruptions are fatal.
有所不同的是，这种激光器与其它脉冲激光器完全相反：在大多数的时间里它是打开着的，但它会周期性的短暂自动关闭。
What is unusual is that this laser is the exact inverse of most pulsed lasers: it's on most of the time, but periodically turns itself off for a short time.
脉冲激光器是另一类的激光器，它的脉冲是在“开”与“关”两种状态的振荡之间产生。当激光器处于“开”的状态，产生光，在“关”的状态，光量显著减少。
There is another class of lasers, however, that pulse, oscillating between an "on" stage, where light is produced, and an "off" stage, when the amount of light is dramatically reduced.
