英语翻译
A laser is used to produce very powerful beams of light.These beams of light are so powerful that they make holes in a steel very quickly.Today laser is getting wider and wider used in more and more fields.
Why is laser so much more powerful than other kinds of light?What makes laser beams so different from other beams?
Laser is a kind of light and also a form of energy.A laser beam is made up of very short waves.These waves all have the same wave length.The laser beam keeps going on and off all the time,and is off much longer than it is on.As these changes are very fast,we can not see them.During the time laser beam is off.The energy for the next burst of light is being built up,so when the beam is on again,it will be a strong burst.And the laser beam doesn't spread,that is,it doesn't get wider as other light beams do.This is why the laser beam can keep all its energy and is so much more powerful light beams.

激光光束被用来生产具有强大能量的光束.这种光束是如此能量巨大以至于他能快速的在钢铁上制造洞.在今天,激光被广泛应用于越来越多的领域.
为什么激光比其他的光更强大呢?是什么使激光光束不同于其他的光束?
激光是一种光和一种形式的能量.激光光束有非常短的波组成,这些波全部都波长一样.激光光束一直保持上升和下降,然后会越来越长.这些变化都是非常快的,我们不能看见.在激光光束结束的这段时间,下一阶段光爆裂的能量正在逐渐获得,所以当激光光束再一次开始时,他会是一次很强的爆发.激光光束不会传播,这就是说,他不会变得想起他的光束一样越来越广.这就是激光光束能保持它的能量,且比其他光束更强大的原因 .
