When laser intensity reaches a certain value, chaos appears and makes DNA mutate.

当激光强度达到一定值时，出现了混沌，会激励DNA发生变异。

Darkening and refractive index change varied with laser intensity, scan speed and line interval.

暗化程度和折射率改变随激光强度、扫描速度、扫描行间距变化而变化。

So we see that we do not eject electrons in the case of the laser pointer, even if we have this intensity, it is still not related to the energy of an individual photon, so we won't see an effect.

所以我们看到我们用激光笔,还是没有逐出电子，即使我们有这样的强度，它仍然与一个单个的光子能量无关,所以我们不会看到光电效应。

Also, what's the energy per photon of this red laser pointer, and then it's also worth trying a calculation dealing with intensity. So let's also try calculating the numbers of photons that would be emitted by this laser pointer, if, for example, we were to use it for 60 seconds and this were a one milliwatt laser.

同样，红色激光笔的,每个光子能量是多少，这也值得用处理强度的方法计算一下,让我们也计算一下,有多少光子会从这个激光笔射出，举个例子，如果我们使用它持续60秒,这里会有一毫瓦的激光。

While many may be focusing with laser like intensity on Switzerland, it is not the only game in town.

Once the cancerous area is precisely targeted, only the intensity of the laser radiation needs to be turned up in order to irradiate, or burn off, the tumor.

ENGADGET: Researchers develop femtosecond laser that can diagnose, blast cancerous tumors

The other two methods rely on specially shaped laser beams - instead of a beam whose intensity peaks at its centre and tails off gradually, the team is investigating two alternatives: solenoid beams and Bessel beams.
