Re: Why is 445nm a better wavelength for burning than 405nm

It's not necessarily better at burning (as most people have said), but it may just be a result of the fact that the highest power we see commonly in 405nm is 700-800mW, and in 445 we see upwards of 1.8W, which is significantly more. Even though more energy will be absorbed by the target per photon of 405nm, there are so many more photons of 445nm that the 445 will probably burn much more quickly than 405nm.

However, of equal power (mWs), yes, the 405 will burn quicker, generally speaking.

I agree .. it's not better. As for shorter wavelength having more energy .. that is true, but since we classify lasers by power, not photon count, it's irrelevant. 1W is 1W, red, green, or blue .. for blue it will just need less photons to achieve 1W.
Differences are in absorption. Blue is absorbed better by most materials then red, or green. But then 405 is usually absorbed even better (ie it burns better). On the other hand, there still may be materials, which wont be burned well by any of these, and would be quite vulnerable to red light .. it simply depends ..

Because they do

Way to revive a dead thread, Taco.

It was only dead for a little while :yh:

I guess. I wonder why Taco became banned so soon .

Why you guys always bump these old crappy threads?

Misread something on the Wickedlasers HP, they were talkin about skin hazardous.

:beer:

Beats me,... but I love my Pomeranians, chocolate is okay though!

 

[Flaminpyro]

Paomeranins are ok, I love CATS they taste like chicken

 

[borgqueenx]

What the hell is this?
We should ban djny for this mispost!

Cadbury chocolate > Hersheys chocolate.

3...2...1...FIGHT!

i don't understand this thread........

 

[Lotus_Darkrose]

I think the thread title was changed from the original

Sorry if you already knew this

Milk Chocolate < Dark Chocolate

 

[Lotus_Darkrose]

Mmmm...chocolate

 

[budabob07]

Umm... what does chocolate have to do with 445 nm lasers?
