Different laser wavelengths which band burning something stronger?
Different laser wavelengths which band burning something stronger?
405nm has the most powerful to burn object, but portable laser cannot be made to very high output, low beam light, even cannot be seen in daytime.
2W near infrared is very powerful, but divergence, beam spot almost invisible;
The high power of 532/635/650nm, can be long distance to burning object, the effect much better than blue.
445nm, single photon energy is very high, so as power, short distance burning is the best, but the burning ability will decline when the distance being longer, but with the increase of output, the long distance burning effect will gradually catch up the low power of green.
Which color laser beam brightest?
Which color laser beam brightest?
Human eye is most sensitive to green light.
So the same power laser beam, green laser beam is the brightest.

The High power laser pointer can burn match / detonated balloon / burn cotton swab
The High power laser pointer can burn match / detonated balloon / burn cotton swab
Experiment 1: 500mw green laser pointer can burn match
We tested three laser pointers, they are 5mw green laser pointer, 50mw green laser pointer, 500mw green laser pointer. And we found out whether they can burn a match.
It’s a close test, the laser beam is a serious hazard to human eyes. We need to wear the safety glasses.
We use 5mw green laser beam aim at the match head, after 1 minute, the match has no any reaction. Then we use 50mw green laser pointer do same test, and we have got same result, the match has no any reaction.
In the end we use 500mw green laser beam aim at the match head, in 8 centimeters, less than 3 seconds, we saw the white smoke from the match head, immediately the match burn out.
Experiment 2: High power laser pointer can detonate balloon
Put the balloon on the table, we use 5mw laser bean aim at the balloon, after 2 minutes, the balloon has no reaction. We use 50mw laser pointer do the same test, and we get the same result, the balloon doesn’t have any reaction.
Then we use 500mw green laser beam aim at the balloon, less than 3 seconds, the balloon detonated.
We use 500mw green laser beam aim at the cotton swab in 9 centimeters, after 10 seconds, we saw the black smoke from the cotton swab, it be burned.
Warning: Never let the children pay the laser pointer
The laser pointer themselves are completely safe. If wrongly used. There is a big hidden trouble. Especial the high out put laser pointer.
