AT is the best color for burning capability??? i heard that the best is bluray violet laser... that can burn a WHITE paper....

should be fine to know what is the best color... and a list of color that EACH color burn better.... 4 example... PRO color for green laser and CONS color for burning capability.

some months ago i thought that blusay laser were expensive.... but now.. i see cheap laser pointer bluray. how is visible the beam?even IF...is visible. some chinese site like rayfoss sell 100/120mw laser bluray at not so much price.

umm....have you tried using the search button?
There are so many threads out there about this.

There are a lot of variables. I can't explain it.

English, mutha-fu*ka. Do you speak it??



Oh, and in my experience blu-ray diodes burn better at lower powers than most other colors.

less wavelength (quantum energy increasing) - better "burner" for your logic.

Technically the lower the wavelength, the more energy density, so it should burn better for the same power output... In theory a 100mW bluray is stronger than a 100mW red, though in reality there isn't much difference. For the most part output power means a lot more about burning capability than anything else. 100mW = 100mW regardless of color.
Another thing is different colored objects absorb different colors of light. A red object for example absorbs every color except for red, since it reflects red light, it appears to our eyes as red. For red objects, a red laser will not be able to burn them very well, since most of the light is reflected away, not absorbed by the object. Black objects absorb all colors, so all colored lasers will burn black objects just as effectively. White objects reflect all colors, so no lasers will be able to burn them very well, although bluray seems to be absorbed, so bluray is better at burning white objects than other colors.

As far as visibility goes, the human eye sees green much brighter than any other color, so green lasers will look much brighter at lower powers. Bluray is on the very verge of being invisible to the human eye, so even very high powered blurays aren't very visible.

These are all very silly questions which you can answer for yourself by taking a highschool physics class or reading the forum before posting, that's why we made fun of you, not because of your english, but because these are dumb questions that we answer every day because people seem to think it's easier to ask a question than to answer it themselves by simply reading.

You can easily find hi power reds that burn well, but they are a longer wavelength than green or violet. Green, having a shorter wavelength than red, is (in plain terms) better at burning. But our eyes are super sensitive to the color green, which can make them difficult to use while burning (eye fatigue) without your proper eye glasses protection. I like Blu-ray violet, since it is the shortest of the typical wavelengths used here, and since the dot isn't so intense on the eyes.. hope that helps!

It's weird though, that to some people (myself included) the beam from a blu-ray is extremely visible from about 50mW on up without smoke/fog.. I know it has to do with Rayleigh scattering and the short wavelength (the reason the sky is blue). To me it's an added bonus. The way I perceive it, the beam from a blu-ray laser is more visible from more angles than any red laser, and it's visible even when perpendicular to the beam. It just makes blu-rays extra cool to me.

Same for me, the blu-ray seems more powerfull than my red at 200mW.

I guess it depends on the way you see colors, I bet it varies between people quite a lot.

This topic is has been made so many times before, and is a great example of why we should have mods who can lock/delete unnecessary threads that clutter the forums.

i dis-agree with firemylaser. forums are about discussion. And this thread has brought that out.
