The laser, with its beam of strong light, can drill a hole in a diamond, and yet can be so well controlled that it can be used in delicate eye operations.

凭着本身强烈的光束，激光可在钻石上钻一个洞，而且可以被很好地控制，因此能用于精密的眼部手术。

This gives you a little bit of an idea of just how many individual photons there are in a laser beam of light.

这让你对一束激光中有多少个光子有了一点概念。

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

So this gives you a little bit of an idea of just how many individual photons there are in a laser beam of light. This is a huge number of photons.

这个给你们一点思路关于,一个激光束有多少独立的光子,这是一个巨大的光子数目。

It's as if this celestial laser beam were designed so as to actually shift the atomic structure of the pure corporeal frame of the virgin's body until that body is so rarefied, so pure and ethereal, that it's nothing but soul.

这束天国的激光好像被设计成,去把处女纯净肉体的原子结构,变的纯化，纯粹和飘渺，那就是灵魂。

In the researchers' new imaging system, a beam of infrared laser light is widely dispersed throughout a room.

ENGADGET: Infrared holography lets rescuers see people through walls, fire, walls of fire (video)

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 (even by the exacting standards of a normal laser beam) and can thus be focused onto a small area.
