Every molecule gives off its own unique vibrational frequency in response to the kick from the short pulse.

每个分子都会对短脉冲的轻击产生应激，发射出独有的振动频率。

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.

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。

"I said to him maybe he's taken his finger off the pulse because he didn't know what was going on!"

Any electrical or electronic device - including the grid's transformers - not shielded against this pulse would be, at best, taken temporarily off-line.

Here at CES 2013 the company is showing off a concept smartwatch that uses an ECG sensor to measure the pulse in your wrist.
