I'm an IT Analyst currently living in Texas. Originally from Penzberg, Germany. I love the fact that I get to play with computers and get paid for it! I have a bit of experience in electronics, but I only recently started building lasers in the last few months. (Had several computers laying around the house and office with busted DVD burners. (drive moters) My wife tried to throw them away. When I told her not to, she gave me 2 days to think of a use for them or I had to get rid of them. That ultimatum led me here, and I'm betting she wished he had just tossed em before I got home from the office.)

I am working on my 3rd build now.

I have been lurking around the forum for a few months, and pounding the heck outta the Search button. I want to go ahead and thank everyone here. I really have learned quite a bit from you guys.

:thanks:

Regards,
Brandon

Welcome:

to the forum.
I hope you have fun and learn a lot. So, do you know the approximate output (in mW) of your first 3 laser builds? Or the input current you set them at?
Reminder: always wear safety glasses when using high-powered lasers. :cool:

No... I do not know what they are putting out. I am about to build a proper dummy load, and I do not yet have a meter. If anyone can suggest a good meter I would appreciate it. I would like to order one this week while I have some extra cash laying around that my wife hasn't found yet.

The first build used a diode from a 16x dvd burner. This was really a practice run. The second used a diode harvested from a 22x burner.

Both are in a Coleman Max LED flashlight (one at 3V and one at 4.5V) host with an AixaiZ module housing. A Rckstr driver on the 22x, and an O-Like driver on the 16X. I believe I have the O-Like driver at approx 2.5V/150mA.

Anyone have a rough idea what kinda power you can safely get from a 12x diode? I have been searching around for an answer to that question without much luck.

Welcome to the forum. It's always nice to see people reading up first, it makes explaining things easier. :beer:

In regards to your question, 12x DVD diodes are considered antique, and you really can't find graphs for them. Heck- I don't even think LPF was around when they were around.

The general consensus (extrapolating from existing graphs of 16x and 18x diodes) is that they really shouldn't be taken above 100mA, and I'd regard as the safe limit. But as I said, there's no graphs for them, so it's all trial-and-error.

That could explain why I have not been able to find the data.

I have 5 or 6 12x DVD burners laying around the office that we were gonna throw out. I think I may save them from the trash bin, and see what they can do. I doubt that they will be too spectacular, but it will give me something to do at work. :shhh:

Yeah. That's where trial and error comes in. Start off at 100mA, and lower the current as they start popping :crackup:

Seriously, though, that's about the only way you'd be able to get any data on them.

Okay... Verrrryy important question...

When playing with a 650nm 200mw torch where is the real danger? It is pretty obvious that I should not point it at my eyes, or any reflective serface. Eg. Mirror, pane of glass, still water etc. where the beam could bounce back and ZAP my retna.

I have a feeling that the light reflecting off of a white wall or piece of paper could be enough to do damage. At least over time.

How far off base am I there?

I have 2 cheap pair of glasses from O-Like. $15.00 glasses for red light, and a $45.00 pair I got for 405nm light. Still I do not feel protected. Even with those glasses on I get the creeps from time to time. Can anyone tell me if I am being over cautious or should I find some better glasses?

I have no idea how well the O-Like goggles for red work, I've never seen a pair, and neither has most of the others here.. The 405 O-Like pair do work well, though, or so I've heard.

While 200mW shouldn't do damage from diffuse and scattered reflections(even over time), it can be extremely uncomfortable to look at without goggles.

If you want some good, cheap goggles that are known to work, head over here:

But just remember- even goggles won't save you from stupidity. Common sense is the most important part of it all.

Thanks much... I'll check it out. I really do want to order another pair. I just do not feel comfortable trusting my eyes to a $15.00 piece of plastic. I only have one pair of eyes ya know. My wife is kinda cute... (IMO) I'd hate to not be able to see the goods.

(She just smacked me on the back of the head...)

Meh. I'm not big on the Dragon Lasers goggles. I have a few pairs, a pair of the cheapo focalprice ones, and the "eagle pair" ones from zonestealth. After using (and comparing) all of the different safety glasses that I have, I feel the Zonestealth ones are better quality and provide better protection (than other inexpensive ones):
Protection Glasses for 650nm Red Laser

Of course $157 OEM ones will provide certified protection:
DY2 - 585nm, 650nm, Red Diode [NR-DY2-EN207] - $157.50

I have come across a few pair that will work with both 405 nm, and 650 nm. Anyone have a good pair that will absorb both wavelengths?

And cosst less than $100.00?

i was gonna say, my DL glasses for 25.00 make my 1.9W 445 look like a tiny dot. they are perfect for 405-532 and work beautifully. and im sure there ones for red work wonderfully also.

No I WAS not planning on a dual color laser... Stop giving me ideas! :beer:

I asked because I have too many toys as it is, and in some cases it can be cheaper to buy one pair instead of two.

BTW JakeGT... I did see a pair on DL's sight that is raited for 405nm, and 650m.

Thanks guys.
