Alien laser bult me a 7 watt 445 with an open can diode for a adult friend. Dust got in the diode and killed it. I messaged him about getting it fixed, and was waiting for an address to send it too when he tells me he has moved to Europe, and lasers are no longer his hobby. The driver is set to 5 amps, and I would like a 7 watt closed can 445nm, a 1.5 watt 520 closed can, or a 5+ watt 470 direct side closed can put into it. The host uses two 16340s, but i would like it modified to use two 18650s. Here is the laser. https://www.youtube.com/watch?v=hMu_8Y24y8U The reputable builder with the lowest offer will get this build handed over to them. Anyone up to it?:)

I asked him, but he never told me the diode model. I am not sure what it it was. I want the new diode to be a closed can.

Besides, closed can is actually IMO not as great as everyone makes it to be. I prefer open can diodes because besides the lens there are no other direct obstructions or possibilities for them such as any kind of foreign matter on the diode window. Can you give any more detail to the problem other than "dust"?

I talked to alien about it before he quit. I took the lens off to solve a focusing issue. This exposed the delicate diode to the outside. The lens was removed a few times(i didn't know these diodes were so sensitive until i learned the hard way). it could have also overheated. Again, if you have doubts about my friend, give me your number and i will have him call you. He had never used high powered lasers before i educated him. Transactions were to go through me due to more experience. Don't worry, I bought two pairs of 0d6+ glasses. Doubt me if you wish, but gif you choose two, you are the only ones being fooled here.

Funny as you gave me a negative rep a few days ago.
Yes I did, for a valid reason. The post you made was useless. This does not mean I am against you, but you need to keep things civil. It seems as though you are easily aggravated, let's not turn this into a huge drama thread.

Also, you should edit your posts to prevent double posting. It is looked down upon here as it is against forum etiquette.

Putting the inane drama aside, the diode you might need is a bit expensive for a lot of people to work with. I'd say it was the NUBM44 which is $110 from DTR.

Are you absolutely sure the diode is blown? What about the driver?

I think you might be best off testing the diode with a supply or new driver yourself first. If that doesn't work, ordering a new diode and pressing it in yourself is fairly straightforward. There are plenty resources and members on this site that can help guide you.

THE REP SYSTEM IS NOT MODERATED.

The Reputation system is not subject to content moderation.

Whether you received a positive rep, OR a negative rep, do not report it unless it is in direct violation to LaserPointerForums Terms of Service agreement.

Specifically, this means unless it is a threat, or involves vulgar language, the rep will not be changed or removed.

The best way to deal with a negative rep is to contribute something positive to the community, to earn positive rep.

In plain English: NO COMPLAINING!

The mods can't babysit every little boo-hoo.

Apparently no one bothers with sticky threads...

Ever since that accident i have been much more careful. When outside, i keep the dot at least 5 or so feet away, but if it is that close, i only observe it briefly. Mainly, I point it in the sky(away from planes of course), or at tall trees. When burning, i always use safety glasses. The past incidents made me more aware of the dangers of class 4 lasers, and i thank you for that. With the proper safety in place, class 4 lasers can be very awe inspiring.

Definitely. Class IV lasers are the most awe inspiring, and they also demand great respect. Nobody wants you to leave the forum over this petty drama. Just stay safe with big scary lasers and develop strong safety habits. Sounds like you're already on the way, having had some close calls. Sorry about your 7W laser btw. Sucks that the seller went to europe and can no longer help you.

Accidents can happen when you least expect it, when you let your guard down for a moment.

We have all had those 5mw red pointer oops moments, those are important learning moments because even 1/10 of 1 watt can blind you forever, so it is a very big deal, and even worse if you hurt someone else.

Everyone makes mistakes, but with some things you must not allow a mistake to ever happen and that means safe habits, double precautions, and being always vigilant.

The radical divergence of these diodes has no doubt prevented a lot of through the bushes accidents, but with higher powers you can't depend on distance saving you from doing damage, so you need to think like it's a loaded gun and never let a stray beam get away, it could come back and find your eye.

Na listen son, just stick with low power lasers for now. No one needs a 1 watt laser to enjoy them. 1 watt may seem like a low power these days but it still is a lot of power and enough to cause serious damage even when you think you're prepared. Accidents are exactly that, accidents. They happen when we don't mean for them to happen. Having safety goggles is a good start towards safety but it doesn't prevent all accidents. For now I suggest you stick with max 200-250mw. Just grow up a little before you take on the bigger ones. Sound good kiddo?
oh, and sorry about bad rep. Would positive rep you but it won't let me.

Another thing to keep in mind is to not share the laser with anyone who doesn't know about the dangers. I've had a scary experience with a 100mw 532nm nova penlaser of all things. I was shining it around outside and my cousin wanted to try it out. I gave the usual lecture about not shining at people/planes/reflective objects etc. Guess what the first thing they did was? They went and started waving it all around at some parked cars within 20 feet of us and sending a bunch of reflections all over the place. That might have gone really badly, had it been a >1W laser.

most people who want to use one of mine no longer want to after the safety lecture I have to give. once I did go over everything I could think of, and handed a friend my 50mW 589nm. you know how when changing targets outside you should switch the laser off, change targets, then switch it back on? (unless you know ALL the surfaces the dot will land on are ok to point at) well they didnt do that, and i had a cringe moment similar but less severe to those youtube videos of someone pointing a 1W laser randomly over a bunch of buildings and their windows. glad it was a 50mW one they did it with, and added one more thing to mention in the safety lecture.

I thought it'd go without saying, akin to keeping a full auto gun on full auto between targets, but in a sense worse due to the fact it's constant wave, not pulsed. i guess it's a good idea to explicitly state, even if you've told them already to basically treat it like a gun

yes agreed. In fact, i was thinking 5 feet was two close, maybe more like ten. I used to use it inside our garage with no glasses(to se how bright it is) but since there are shiny objets, i will discontinue this unless i have glasses. I still do use it inside with no glasses when theres a diffraction grating on it(split into many beams) Though. If someone could right out a few rules, that would be great. The days events have really woken me up, and i thank you guys for that. i also want to appolagize for the mistakes I've made and drama I've caused. I feel that with a little practice, i can safely enjoy the beauty of these devices, and the unmatchable spectacle they create. Thank you.
