Precautions for the use of high-power laser pointers
The wide application of high-power Laser pointer has brought a lot of comfort in relevant fields. However, malicious use of high-power laser pointers is extremely dangerous. This will not only endanger people's health, but also cause unpredictable damage. This is why high-power laser pens are harmful to society. Therefore, it is very necessary to popularize laser knowledge to the people.If the high-intensity laser pen focuses and directly irradiates flammable and combustible materials such as gasoline, matches and fireworks, the ignition time is very short, sometimes only 10 seconds, which is easy to cause fire. More serious health and property lossesIn many cases, stimulus measures have fallen sharply due to high temperatures.

The output power of the first stage is lower than 0.4 MW, the output power of the second stage is - 0.4 MW to 1 MW at the weekend, while the output power of the third stage is from 1 to 500 MW, and the fourth step is more 500MW. If you can't export more 0.4mw laser to directly irradiate your eyes, it is easy to damage human eyes when the export reaches level 3. If the driver irradiates the laser pen with high productivity within three seconds, you can light a match. If it is dangerous, it can also be used to light matches. In the experiment, the reporters found three balloons, put them on the table and fired them with a 5 mW laser pen. After two minutes, they did not change, and then with a 200 MW laser pen. About two minutes later, the balloon did not change. Then, using a 1000 MW high-power laser pointers, within three seconds, the balloon exploded and many fragments exploded in the air. In the range of 9 cm, 1000 MW high-performance laser is used. After about ten seconds, the cork began to smoke and turn yellow.
