Real high energy lasers would be invisible since they operate outside outside the visible range of light.

真正的高能激光是不可见的，因为它们在可见光范围之外运行。

Imagine for a moment that I'm a beam of light far outside the visible range, traveling from a star in a distant part of the universe.

想象一下， 我是一束远在可见范围之外的光，从宇宙遥远部分的一颗恒星发出。

Our sun is about 5800 Kelvin, and the radiation it gives off is centered in the visible range… which is exactly why it's the visible range, because that's what we evolved to see… but I digress!

我们的太阳大约是 5800 开尔文， 它发出的辐射集中在可见光范围内… … 这正是它是可见光范围的原因，因为那是我们进化的目的… … 但我离题了！
