Re: FS: >80mW Blu-Rays, two models: GONE!

Well, i sure hope so.


The manufacturing might begin tomorrow.
I'm probably gonna ask everyone to pray...

Re: FS: >80mW Blu-Rays, two models: GONE!

BTW, after i realized the measuring error, i repeated the no lens measurement.

When a Blu Ray is putting out 87mW through a clear acrylic, the actual power of the diode is over 131mW!
And they are capable of more than that.. At the expense of a shorter life most likely...


So it's "just" a matter of capturing as much of this light as possible, and bringing it out. There are some losses even in a glass lens of course, but they will be much smaller than with plastic. And the coating will reduce the reflective losses.


The lens design software says, the lens will do fine with our diode, so this could turn out to be a great lens for this hobby, and hopefully not just for Blu Rays.

There! I'm better now.

have you guys have no respect for my clothes they are now covered in drool ;D ;D

Re: FS: >80mW Blu-Rays, two models: GONE!

Well, that's just the power BEHIND the lens. But not sure if it's total power, cos of the AixiZ module walls obstructing some of the spreading light - the light spreads more on one axis, and hits the threads inside the module. I need to do some tests with diodes, that are not in modules yet... Should be interesting!

Of course, no lens can bring all of that out. But since these diodes can obviously live at up to 130mA, i'm pretty sure, a good lens would allow reaching up to 150mW with some overdriving. Maybe more than that, don't know. I wouldn't recommend trying of course, but the diodes are relatively cheap in comparison to a 6xBR writer diode, so i'm sure some people will try.

A week or two ago, 150mW of 405nm was only thought possible with a 6x. But with a good lens (like the Meredith and hopefully the custom one), i think a 6x could reach close to 300mW! Seriously! I mean, they are reaching >200mW with acrylic lenses (Hemlock_Mike & Wannaburn), and those would seem to take >1/3 of the power away! I had no idea, that 405nm diodes in drives reached that power already. They must be overdriven quite hard for this of course, but with a good lens, a 6x could reach 200mW much more easily... It's a shame to drive a diode harder, only to lose 1/3 in a plastic lens.



Anyway, i got the invoice for the lenses, and was a little disappointed, when it said "five weeks". I was pretty sure, they said two before. But today i heard two again.


So two weeks + shipping to me, and then we'll know for sure!

Re: FS: >80mW Blu-Rays, two models: GONE!

So the red & Blueray diodes are getting similar ^^ Neat!

Re: FS: >80mW Blu-Rays, two models: GONE!

yeah that's a bit strange. The 6x blu-ray's are close to the output of 18x red's, how's that possible?

Igor, you just know to get me more and more excited every time! [smiley=beer.gif]

Yeah, that's exactly what i was thinking about! The 6x can be pushed almost to the power of an open can red! It's just that there are more losses in the plastic lenses at this wavelength. A 6x at this power probably wouldn't live very long, but 200mW is reachable at a much safer current with a Meredith lens, and hopefully with the custom lens.

Just imagine what the 8x and the 10x drives will be like!

Why wouldn't it be possible? Just a week ago i was reading the datasheet of a 1W 405nm diode. It was multimode, and the 1W power was max peak power, but still!


I don't know how, but i can tell you why.. A Blue Ray disk holds an enormous amount of information. There are many more microscopic dots on the surface, where the laser has to create a change, to write data, than o a DVD, even tho the surface is the same.

For the drive to write all this info to the disk in a "humane" amount of time, the laser has to be very powerful. The faster the disk spins, the less time the laser has, to create the damage on it's surface. So it has to be more powerful.

And then, there are all the losses in the MANY optics inside the sled. The power is reduced a lot, before the beam ever reaches the disk. Especially, if some of the lenses should be plastic! And at the last step, part of the beam is obstructed with an LCD window, to give it the perfect shape, to write the microscopic dot.

We are using the total power of the diode, weird shape beam and all, and with only one lens in between. Make that lens good, and you have a very powerful laser..


Another factor is reliability. A diode is meant to work within it's ratings for a VERY long time inside a computer drive. To achieve this, it has to be capable of much more, than is actually needed.

But we are driving them close to the edge, of what they are capable of. So we get more power at the expense of a shorter life, and sometimes, risk of instant failure....

Hehe.. Well, i'm excited myself!

Re: FS: >80mW Blu-Rays, two models: GONE!

This is so cool!

IgorT i wish you the best of lucks with these lenses!!!!

Re: FS: >80mW Blu-Rays, two models: GONE!

Thank you Niko!


Anyway, at the moment i'm working on all the free stuff i promised everyone. Taking me almost as much time as the lazors themselves.


Also, WikedAlex already got one of his lazors from me (now this was FAST shipping!), and he is preparing some match lighting videos now. This laser is not the gray mini laser, but a box laser, that i made as a trade for some diodes, but it has the same power of >80mW.

Yes an her is the video http://www.youtube.com/watch?v=LqdmsYoFr7g
I can't waith for the silver one^^
The 80mw burns very good (the video was made with almost empti batteris)
Thank you Igor!

Re: FS: >80mW Blu-Rays, two models: GONE!

I'm glad you like it. You make nice videos btw. No wonder you earned so many Wicked Bucks with them..

If the battery was empty, the driver might have dropped out of regulation and the current went down. I should have included the Low Battery warning LED, but you were so impatient, that i forgot... Sorry. I can send it to you and you can add it yourself tho. You would just have to drill one hole and solder two wires.

Get some high capacity Ni-MHs and use one while charging the other.
