Laser Goggles Slightly Exaggerated?

Morgan said:

You cannot look at a 1 Watt spot whilst burning. I do not believe your laser is anywhere near 1 Watt. Can you link to a review of it or give us some details about how you know it is 1W?


Nope, but then again, the diode from a Lite-On, 12x Bluray sled isn't a 1W diode and doesn't claim to be. You may get it close but it'll burn out real quick. Maybe you backed out of the GB when I told you there was no gaurantee and that if you break it, it's the only one you'll get? I'm glad you did but then again I was surprised to see your interest anyway.

I was answereing many questions at once.
XJ-A140
Boostdrive maxed out pot maxed out setting
AixiZ 445nm Glass

I do not have a 5000$ LPM So I wouldn't know but that is my guess (~1W).

I backed out because I didn't know how to harvest it. I do now though. Also I didn't have a host to put it in so I didn't buy until I had a host.

boostdrive maxed out pot maxed out setting - do you mean microboost? Maxed out settings? 1amp or 1.2amps? Photos or it didn't happen...
aixiz 445nm glass

i do not have a 5000$ lpm so i wouldn't know but that is my guess (~1w). - no need to spend that much. About $300 should do it...

~1.1A? I dont remember exactly. I turned the pot to the stop. For some reason it wouldnt measure in mV so I measured in V and it was at 1.10 or somewhere around there. Do you really expect me to pull my laser apart and connect to test load to prove a point?

If you do, you are insane. I will post a video of it burning.

Also $300 is a lot to prove a point. Its bright as shit and it burns things.

In that case, and not to exaggerate, you'll need to be wearing goggles then... Won't you?!!!

Ta da lol I know its hard to see the burning cuz my hand is in front but the process isn't the point its the fact that it does do it. Video Here

Sorry If you cant open, you tube takes forever, this is instant

*sceptic* the instant match light is convincing buuuuut those materials could have had a hole in them already

omg lol You can see theres no hole when I run it across and the light flickers through as I move. I will make a better vid when I do my review (Classes and work got me tied down)

whenever u can

And you're doing that WITHOUT goggles? :thinking: Regardless of the power, this is dumb!

It is impossible to prove the output power with a video and I cannot say it definitely isn't 1W due to this but I still don't believe it. Those tricks can be achieved with a lot less than 1W in any case. Just because you have maxed out a pot and read 1.1V on a testload, (I assume that's what you meant in a previous post?), it doesn't mean your laser outputs ~1W. It's nice to think this might be true, and it really could be, but it could also be a lot, lot less. Look around for the figures; there are perfectly healthy diodes being run at 1A and only outputting 800mW with a lens that shows 15% gains above the Aixiz 445, 3 Element Glass one you are using. That could put yours below 700mW even... And that's assuming your diode is healthy.

To convince anyone who knows, you need an LPM. You don't even have to go to $300 these days. Mariomaster has one for a mere $100 but you have to calibrate it to a known output laser and if you tell it that the laser you have there is 1,000mW, then your meter will read 1,000mW quite happily, and be wrong about it all day! If you go this route, get it calibrated by a member who can do it properly for you. Then post a readout...

Just because you want it to be ~1W, don't make it so.

Answer 1 question at a time... it simplifies the answer and makes
it less confusing...:undecided:



You don't need a $5000.00 LPM... this one will do the job nicely
for a He!! of a lot less... or get MM's LPM for a "C" note... it should
be good enough for your use.

If you have no concrete proof that your laser is 1 Watt then
don't state it... It makes you look like a noob...

If you don't have the funds to by the equipment needed to test
your laser then send it to a member that has a calibrated LPM..

You stating that it is 1 Watt does no make it so....
As to the Burning video... that proves nothing...
I have a 30mW 405nm that buns wood and plastic...

You seem to go about your Electronics and testing without
any research and it makes you look foolish...
You can't possibly be that lazy...

BTW... have your entertained the possibility that your Laser
may not seem that bright to you because you have already
damaged your eyesight.....

I was exaggerating, makes a story better. I dont have 319 thanks but no thanks Down the road I am going to make a good high power 445, at 1.5A Flex (How much longer you think these diodes will be available for?)

Hey Jerry, :wave:, I wasn't overlooking your great meter, (that I aspire to myself when funds are available ), and mentioned the $300 dollar mark in the post below the one you quoted there, in the hope Toaster may go looking. Still seemed to be a bit pricey to, 'prove a point', for him though.

It's actually an extremely useful piece of equipment in my opinion and should be saved up for. Not everyone can afford one immediately but ownership is not about proving a point; it's about testing and measuring, isn't it? This is science-y stuff and not speculatory stuff, am I right?

Only to be purchased after goggles though...

N/P Morgan....
I agree... if you can afford to buy or build a Laser that could
possibly harm (blind) you... you would think the first thing you
would purchase is a pair of Laser Safety Goggles so that you
can enjoy Lasers for a long... long time..

And if you want to get more technical and state facts about
your Lasers then get a calibrated Laser Power Meter...

If a member claims that a Laser is XXX mW then prove it by
having the equipment to back up your claims... or shut up...

This is not a women's meeting where each one brags about her
husband's penis is larger that another... Prove it...

If you can't or don't want to provide proof then don't state
facts you can't back up...

Wow, I am constantly amazed at how quickly people in this forum are to brand someone a "troll" and think they are purposely trying to mislead everyone. It seems like anyone who doesn't see eye to eye with the regulars or who shows ignorance about the inner details of laserology is a troll - especially if they stick up for themselves.

I almost laughed when a few of you actually thought Toasty was faking his video.

He may be trying too hard to convince us (and really he's more trying to convince himself) that a high power laser isn't really THAT bright and that goggles aren't totally neccesary, but that doesn't make him a troll or a liar or a bad guy. He just doesn't want to wear goggles and is trying his best to paint a picture which will make ANYONE here tell him "oh well if you live in a house with no reflective surfaces by all means go right ahead!" (it was pretty funny when you tried to convince us that you really do live in a matte-finish home. Seriously, give up on that one, everyone's home has hundreds of reflective surfaces whether you are aware of it or not).

Toasty, NO ONE WANTS TO WEAR GOGGLES. It sucks. We all want to stare at the pretty lights. I'm sure plenty of people out there will play with lasers their whole life, never wear goggles and never have a problem.

But if fortune doesn't smile upon you and your luck turns for even one second, a little laser goblin in the shape of an eyeball is waiting to pounce. And there is no turning back when that happens - once the zombie bites you, it's all over.

Even if your laser isn't a full watt, clearly it's very powerful. If it lights a match in less than a second, just imagine what a split second of contact with your eye would be like? Thats basically an entire lasik session, after which you could have permanently altered vision.

The problem is these "toys" are only going to get cheaper and MORE powerful and, because that's just the way it goes, before you know it all of us are going to end up with TWO WATT yellow handhelds.

That alone is reason enough to get in the habit of using eye protection; sure, maybe you can dodge the bullet and go commando with the lasers you have now, but in 2 or 3 year you'll have one 2 or 3 times as powerful and that bad habit is going to backfire.

Everyone who puts on a pair of goggles I'm sure does it with a frown, just the same we we all curse the air when we put on a condom - but that frown gets turned upside down when you find out she has AIDS and you go "whew that was a close one" but even so you're stuck with that whore because somehow she still managed to get pregnant (god knows if it's even yours) and so you basically had to let her move in and now your studio apartment smells like diapers and the ironic thing is you don't even need condoms anymore because the LAST thing you want to do is share a bed with that disgusting -

Ok, maybe I'm straying a bit off topic, but you get it.

I think only one person mentioned the word troll Mojo and it wasn't me.

Only one person was skeptical, {sic}, that the holes may already have been in the paper. The main point was not that the video was faked; or that Toasty, {sic}, was deliberately trying to mislead, although misleading it is; it is more that claims to a lasers power are pointless unless it can be shown to be true. Trying to convince anyone otherwise, even one's self, is a non-starter and getting into the habit of estimating laser output is not helpful. Especially when you try and sell something on that basis or use it to back up a build.

If you've read any further back into Toaster's inauspicious start here, then you may appreciate why these type of points are jumped on in this case. Trying to reduce the ignorance is the reason misconceptions and inaccurate information are rigorously pulled up. Stating a laser is ~1W without any measurement is a dumb claim.

This applies to anyone.

If a question is asked with an observed basic understanding or effort to work it out/find the solution for themselves; it is answered. If it's a dumb question with no background to back it up or clearly something that hasn't been researched; then it's also answered but usually with sarcasm and instruction to go read. How that person reacts to those responses shows a great deal. Asking if goggles are really necessary with a 1Watt laser is a dumb question and the rest should be expected. Standing up for yourself doesn't make you right. Being right makes you right.

+1 for speaking up. I share is opinion. Sure, safety goggles are important, but where is the fun in point something you can't see?
If i'm scanning around an open field or up into the sky, i want to see the beam.

The only reason i would wear safety goggle is if i'm in an enclosed area where i'm working be working closely with the beam, like burning things.

safety goggles aren't "ALWAYS" needed. Otherwise you completely eliminate one of the most enjoyable things about lasers in....the color.

@lasersbee: Well my 445nm is 874.286mW Though i have yet to test it on any kind of equipment. I get that figure from the "brightness" :crackup:
