From a treasure look, there is a high-power laser flashlight,
According to the seller, it shot the laser,
We can ignite firecracker from ten meters away.
The East-West net is called the Gatlin laser cannon.
It can be said that it is very deterrent.
Focus the laser's focus on the firecracker's lead,
The lead was instantaneous.
Then pull away.
6 meters away, no point;
At a distance of 4 meters , there is still no point;
Go straight to a distance of 3 meters .
Far away,
The main thing is hand shaking, not focusing on
As long as the alignment, all can.
There is no problem with firecrackers. What about fireworks?
Compared with the lead of firecrackers,
The leads of the fireworks are thicker, harder, and tighter.
Can laser energy not light it?
Still is the second, it seems that artifact is really quite God.
This so-called point firecracker artifact,
If you really get it from the children in your house,
Going to firecrackers, will there be any hidden danger?
The experiment continues.
This time, I changed my perspective.
Just focus the laser on the outer shell of the fireworks.
As a result, an unexpected situation occurred a few minutes later.
Firecracker artifacts simply shine on the shell of the fireworks.
But after 15 minutes, it actually turned itself off.
Speculation may be that the laser burns through the outer shell of the fireworks.
Ignited the gunpowder inside.
It's really dangerous.
What if you ignite a bigger fireworks?
If the fireworks detonated other dangerous goods around it?
If you just stand on the edge of a group of children?
In fact, regarding the danger of lasers,
Everyone is very clear!
Before Xiao Bian also saw a test,
Only, it is an ordinary laser pointer.
The power is far from this point.
But even then, the test results at the time were quite scary.
Although it is just an ordinary laser pointer,
But igniting matches and burning clothes are all momentary things.
Zhejiang University of Technology Laser Processing Technology Engineering Research Center
Professor Xiaodong Hu said:
High-power laser pointer addition
Except for the safety hazards of setting off fireworks and firecrackers
Even more dangerous is that it hurts the human eye.
The eye is a lens,
After the laser beam is focused by the lens of the eye,
It will focus on the retina,
Equivalent to the energy density of the collected light,
It increased by several dozen times,
This kind of energy density directly burns the retina.
So, parents are asked to confiscate their child's high-power laser flashlight as soon as possible
To avoid dangerous things happen.
