Laser Cigarette Lighter?

[Tech_Junkie]

Even at 250ma, I cant think of any diodes that will light a smoke.  Definately one of the trickiest builds to ever grace the pages here. I think its time to find my old Zippo

Do your homework...

Meh.
I have a really good idea!
But i can't tell anyone yet because i am going to patent it.

Why mention it at all???
It's at least a 10K investment before you can present it to a company. Even going through one of those inventor companies it still will be thousands and they will probably rip you off. On top of that the high watt diode is illegal to sell in a commercial novelty application in the US. And if somehow someone got hurt, you would be in lawsuit courts till your hair turned grey. Its just not a sound investment. But it would be cool to add your ideas to ours and maybe we can all get some really cool lighters that no one else has. Then if you want you can eBay them, flee market, ect..

If I use my ~250mw red, I can scorch the tobacco inside the end of a cigarette and smell it burning. Not enough to light it though. I refuse to put the cig in my mouth when lighting with a laser, but I imagine with me puffing while lasing, it would light right up.

my LPC815 open can at 420mA will light cigarettes . my other ones won't though....although i haven't tried with my phr yet...

This seems like an implausible idea.  I can imagine it working, in the sense that a laser could light a cigarette but there are a lot of things that could go wrong.  To begin with, it won't be nearly as interesting as you imagine.  At best you may get a bright red light and some smoke which could be easily replicated with a few LEDs.  It is not going to look like a laser is lighting a cigarette, the beam will not even be visible behind any form of filter.

If you skipped on the filter the beam might be visible, but you would be a little too blind to to see it, and the smoke would obscure the action anyways.

It's thinking like that, what keeps the atomic car and the flux capacitor, just out of reach of the common man.

Well, as a consumer product it would be a liability disaster waiting to happen in any case

On the other hand, i do hear rumors that the nuclear powered streetcar will come with a laser powered cigarette lighter as a base option

OK, but who's gonna feed the squirrel running on the treadmill?

Oh there's no squirrel in my design. You supply the energy (it's easier to feed yourself). And who knows, all the running may make you want to quit smoking! everybody wins

So you are saying that there is not a filter that will let you see the beam? Is this based on every color beam or just red?

Well duh!
If it is a filter, it filters out the wavelength, so how would you see it?

What about using two laser diodes.
A 120mw IR diode that does the real burning (invisible and dangerous)
and a 5mw cheapo red that the user sees, but is just for show. (very visible and harmless)

Then you can have a dichroic filter between the user and the beams. -the IR is filtered out, but the harmless red will still be visible.

Good idea, maybe a bit more power needed on the IR side though.

Sorry. Please keep in mind I just joined 10 days ago and I'm completely new to the hobby. My laser is not finished, nor have I ordered my goggles yet. So I have nothing physical to reference from just yet.
I just assumed that the filter would block the harmful IR only and just let the green beam shine through. That's what the main concern is, IR right? I know that some green pointers have a built in IR filter and you can still see their beam clear as day. Is it harmful to view the beam (any color) from the side? Or its it just the reflective light?

You are blowing my mind with these concepts you have come up with. If we ever get one made we will have you to thank. Good work.

Good luck fitting a green module in there...
It isn't just a diode, you know...

It is not harmful to view the beam, but reflections are harmful.

EDIT:
If you are going to use a green, it would do more damage to your eyes than the IR :

Me Thinks................

 before you tell a long time member with over 1190 posts to do his homework... :-?
you should have perhaps done the same...

Those 532nm lasers in the videos you linked to....  use a hell of a lot more current than 250mA as
referenced by the person who you say didn't do his homework...

The subject wasn't... It can't be done.... but... It would be difficult to do with only 250ma.. IMHO

BTW... the Jerk in the second Video wasn't even wearing protective Laser eyewear... :-?

Did someone forget to mention that green lasers do not use green diodes, as most noobs think? :
A green laser is DPSS, meaning it has to use a pump diode to get green light. It is a difficult process, where many crystals are required.

You have to use at least a 1 WATT IR diode to get 200mW of green.
That is using the highest efficiency crystals :

Now tell me, how much current does a 1 Watt c-mount require? :

In conclusion:
YOU sir, are the one who needs to do his homework.

With some skillz you can get 300mW from a 1W pump
