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。

So what we end up with for the number of photons in this laser beam of light is 2.1 times 10 to the 17 photons.

这个激光束的数目是,2，1乘以10的17次方。

These range from microwave ovens and laser light shows to home security systems and medical imaging devices. (CDER even regulates laser pointers but not online presentation software, if ever a true risk to human health).

FORBES: If Tanning Beds Were A Drug, They'd Be Illegal

Newer developments in laser technology, such as nonablative fractional resurfacing, in which the laser divides the light up into many smaller pulses, have decreased the healing time.
