Are 405nm better burner than 445 ?

[MikjoA]

Hi,

I'd like to buy a new laser, and I'm hesitating getting a 500mw 405nm laser and or a 1.2W 445nm from lazerer.

Which one is the best burning laser ?
Can both light a fire (without matches) ?

By the way is the Devil RIFLE - 405nm 500mW Violet Burning Laser Pointer from lazerer focusable ? it is not mentioned anywhere and it would be surprise it is not since it has the same body of the 1.2W 445nm rifle laser.

Thanks for further helps

405nm is better burning in general. But 445nm beats it because of raw power. Yes the Riffle can be focused.

The 445nm will be better lighting a fire, but its not easy. We dont have the technology yet to put an instant fire starter in a hand held yet. If, and when they do, it will be big $$$.

The 445 will win at burning up close, at a couple feet the 405 will start to take the lead.
You can start a fire, but it is hard.

Oh well I can't imagine how dangerous it would be..
I'm concerned about safety but I guess the 405nm 500mw is almost as dangerous as the 445nm 1.2w, anyway I plan to uses my 405nm/445nm goggles unless I target distant things.
Thank you!

Ah interesting ! Thanks, could it pop ballons at 10 meters for instance ?
Did you both could start a fire ?
Although our eyes are less sensible with short wavelengths do you think the laser beam of the 405nm is well visible at night ?

Sort of like being run over with a sedan is almost as bad as dangerous as being run over with a bus... at the end of the day you're still dead.

Yes, yes, and depends on ambient lighting as well as air particulates, but in general yes.
