Does the sun rise in the East?  Does a Brown Bear sh*t in the woods?  Is a frog's a** water tight?

Well, since I'm not stupid, I understand that it will be a difference. But if you have a 100mw red and a 150mw red, you cannot see a VERY noticeable difference. My question was not if he could see any difference, but if the difference was VERY noticeable. And according to your ironic answer, it seems it is

Re: FS: >90mW Blu-Rays, two models: OPEN

Well, i don't have a 150mW to compare anymore.. : It's 175mW now.. I also don't have a 100mW here..

I need to make some more lasers, and then i will answer your question..

I understood your question very well. I did not attack your intelligence. I actually assumed that you were smart enough to appreciate lingual humor. Obviously, I was mistaken. The answer to it is the same answer as the one to each of my included queries:

The answer to the question, "Is it very noticeable?", is, "Yes." I trust that wasn't too obtuse for you.

oooh getting vicious there jk mine should be here in 3 days or soo
can't wait

Re: FS: >90mW Blu-Rays, two models: OPEN

Oh damn.. I somehow deleted my post.

Stan, did you read the instructions for undisguising your laser? Same goes for everyone else receiving the modular one..

Make sure you know what you're doing BEFORE you do it. If you don't understand it, please ask.

Re: FS: >90mW Blu-Rays, two models: OPEN

I finally got around to make myself a laser with the new more expensive host, and make some pictures...

This is what the new host looks like. The difference between this one and the ones i shipped out is in the manufacturer.. I kept this one, because protected batteries don't fit in well. The ones i use for everyone else look the same, but the batteries fit in smoothly.

I really like this host, because the difference in the price is noticable in the quality. It's very massive, so it also acts as a heatsink extension. The entire laser module is an 18x27mm aluminum heatsink, which contains everything, and sits in the head of the host. You can see the top of the heatsink around the focusing ring.

Re: FS: >90mW Blu-Rays, two models: OPEN

And some beamshots of an original host laser and a new host laser, both running at the same current of 178mA.

The one on the left is only putting out 125mW at this current. This one was made with a diode, that was too weak to be used in your lasers.. The one on the right is putting out 178mW at this current! Both with plastic lenses!


Both are test lasers, made to see how much abuse these diodes can take.

Re: FS: >90mW Blu-Rays, two models: OPEN

Very clean Igor! That's a nice looking build. Did you machine/drill the I.D. of the focus ring? Or, is that not the AixiZ brand?

Re: FS: >90mW Blu-Rays, two models: OPEN

Thanks! I'm very happy with how they turned out.. The module design worked flawlessly and the heatsinking is great even at 190mA! (0.86W heat dissipation - more than a 16x red)

They are very tiny but very massive! That's exactly how i like my lasers..


That's not the AixiZ brand focusing ring.. I got these from DX.. The AixiZ focusing rings are longer, and if you screw them completelly on the lens nut, the lens doesn't go in deep enough.
I actually prefer the AixiZ focusing rings, just because they are longer, but in that case, i have to glue them on the top of the lens nut, so that it still goes in deep enough.

Lenses have a shorter focal length for 405nm, than they do for 650nm. That's the source of the problem. But it also means, that the NA of plastic lenses is higher than 0.3 with blu rays, which is good, as they collect more light.



Also take a look at this..

 

[jayrob]

Re: FS: >90mW Blu-Rays, two models: OPEN

I did find the same thing about the AixiZ rings being thicker, or longer. I just machine the back of them down so that they are 'thinner'. That way, it allows you to turn the black plastic nut farther into the module to get focus!

Wow! Man, it is amazing that those 803T diodes can give us so much power for $30 bucks!

Please keep us posted now... on how long that diode lasts at that current!

Re: FS: >90mW Blu-Rays, two models: OPEN

Of course.. The first high powered one i made was 174mW at 187mA.. That one worked well for quite a while and even after being kept on for long durations at a time. But then it died just after a powerup.

I lowered the current to 178mA and put another diode in that laser, one that was too weak to use in my builds. It still works, but is only putting out 125mW.
With the latest one also set at 178mA, i was aiming at 150-160mW, as the diode i used was putting out less power during the batch test, and i used a lower current, than with the now dead freak.. So i was quite shocked, when it actually did more power at a lower current!  


Anyway, i now have two diodes running at the same current. One is very efficient, the other much less. This way i will also get to see, if the efficiency makes a difference in what they can survive.

But Daguin had one running at 180mA, and he sold it, and now he has one at 190mA, and it still works! So i don't know why mine died at that current, but obviously the power inconsistencies are not the only difference among them.



I will keep posting updates in my batch testing thread - the powers the diodes reach at a certain current, as well as if one of them dies.
If these diodes turn out to be as sturdy as reds, 170mA or maybe even 180mA could turn out to be a "safe" current.

Re: FS: >90mW Blu-Rays, two models: OPEN

180ma= 200mw!!!!!!!!!!!!!!!!(with the glass lense) minimum hmm anyone thinking about what we will get from the new "200mw" diodes coming out from sharp? hehehe oh riiiite

 

[IgorT]

Re: FS: >90mW Blu-Rays, two models: OPEN

Yeah.. But i lowered the current by 10mA. It's now 168mA, and the power is 171mW..

I was worried it would die like the first one, that was doing 174mW.. Because it's not the current, that kills them, but the optical output. So even tho the diode needed less current to give out more power, it could actually have been in more danger, just because of this.. 171mW after a plastic lens might still be too much.

Dave's diode is doing 180mW after a Meredith, which means the optical power is actually lower at 190mA. That's why it can take more current.



Anyway, Stan, did you read the instructions on undisguising the laser?

 

[IgorT]

Re: FS: >90mW Blu-Rays, two models: OPEN

I prepared instructions with pictures on how to un-disguise the lasers. I sent them to everyone's emails. If i forgot someone, please let me know.

Make sure you read them BEFORE doing anything. It's nothing complicated, but it's better to be safe than sorry.

Also, do not attempt to open the module without special instructions. You could damage it, if you do it in the wrong order. Again, it's simple, but if done the wrong way, it could end badly. Besides, i do not recommend doing so anyway...

Re: FS: >90mW Blu-Rays, two models: OPEN

I did not geth the E-mail.And my laser has not arrivde yet.

Re: FS: >90mW Blu-Rays, two models: OPEN

That's because i'm shipping yours today. Like i told you in an email, i could not use the black host you wanted. It didn't fit. It was too small.
I had to make a different one, meaning i had to make a new heatsink module for you.

You'll have it in two days.
I also have your charger ready, and your batteries charged. Got the flat to round adapters yesterday (DX split the shipment).


You don't need instructions however, as it is not disguised.. That is just for the US and Australia and some other countries.

I sent you more details in an email. The laser i'm sending has 23mW more, than the one i sent to you before.. If you want, i could also set the other one higher, but i would have to increase the heatsinking.. I could also just transplant it into one of the new hosts, now that i finally got them. Here, the heatsinking is perfect. And it would look better, than a brick laser.
