Instead of the occasional light pulse, this new laser has the occasional dark pulse, which lasts about one nanosecond.

这种新的激光器是产生长约1纳秒的暗脉冲，而不是光亮的脉冲。

The length of time the lidar’s light pulse takes to return to the satellite provides information about where the clouds or particles are in the atmosphere.

激光雷达的光脉冲返回卫星所消耗的时间提供了大气中云或者粒子的位置信息。

Analogous to a snow avalanche on a steep mountain slope, an incoming light pulse initially frees just a few charge carriers which in turn free others until the original signal is amplified many times.

像陡峭山坡上的雪崩一样，一束入射光的脉冲最初仅仅释放少数的电荷载子(charge carrier)，这些电荷载子再轮流释放其他的载子，直到原始信号被放大很多次。

It takes about an hour to collect and aggregate the data ( view a demonstration of a light pulse as it travels through an ordinary Coca-Cola bottle).

We actually record and average millions of photos to get enough light, each photo made to look the same via carefully timed synchronization with the light pulse.

Even at the speed of radio (ie, the speed of light), a pulse will travel only a few millimetres in that time.
