FS: >120mW PHR, >170-210mW 6x & NEW 8x Blu-Rays!!

Craig,

While i like to keep the powers reasonable, the 8x can probably safelly go close to 400mW with my medium custom glass lens, which will be available immediatelly after it's reviewed by FrancoG.. ;)


300mW+ would be the power after a plastic lens, but the plastic lens would melt! The 8x's really call for my medium glass lens... And this time i finally feel free to introduce the lenses i actually like... So i am much more motivated to get them done ASAP, than i ever was before (before i felt forced to go for the short FL lenses, which while i have them, i never really used outside of testing)...


Are you really wondering if you should get a ~400mW BluRay? :angel:



P.S. Looks like i'm having the lens nuts completelly custom made by the same CNC shop that made my v3 Heatsink/Modules, as soon as Jayrob figures out how best to mount them in metal lens nuts....

Let me know when it's on it's way Igor. I'll be gone on the 16th, and back on the 23rd...

Although someone will be at my home, they will not be checking my e-mails and forum PM's.

I plan on checking in every couple of days to answer PM's and e-mails, but once I take off on the 16th, I won't be shipping kits and lenses until I get back on the 23rd...

I think we are all good there, Jay...

The lens won't come back from Franco before you return. So by the time it's on it's way to you, you'll already be back.. :)


Thanks again for helping me with this, Jay!



P.S. I'll also include my short FL custom lens and the "Nichia Lens", and pay you to mount them the same way, if you will have the time.

It would be stupid not to make use of the two... They cost a lot of money...

DISCOUNT OPTION!



I have decided, that in the future, i will also offer cheaper FlexDrive powered BluRay lasers...

People don't realize how much time i spend making my own drivers and why, and that all that work is a big part of the reason my lasers cost more...


If i was using ready-made drivers, i could finish my work A LOT faster!
Since i would save time, i could offer those builds cheaper, and in the future i will.


However for lasers like that i CAN NOT guarantee future upgradeability to any and all higher power diodes!
If a future diode should need more than 6V or 500mA, it could not be powered by the same driver.

If you want a cheaper build, you will have to take that into account....

The resulting lasers will also be slightly less stable in power, altho in the latest version the FlexDrive was improoved quite a bit, so this instability will be reasonably low. That's also the reason i am willing to start using the v4 FlexDrive for BluRays...





The other part of the reason my lasers cost more is that i pre-test ALL my diodes on my Diode Analyzer. I collect the full P/I/V data for diode efficiency and even it's wavelength, on a device i made specifically for this reason....


I weed out the weakest diodes, and only use good normal diodes or high efficiency diodes.

Because of that, 10% of all GGW 6x diodes are quickly declared useless. Some peak as low as 155 or even just 138mW at 200mA during pre-testing!! :cryyy:

If i was using random diodes (simply taking the next one out of a bag) and then setting them to whatever current was required to reach the power you requested, the currents would be ALL OVER THE PLACE!


As a result some diodes would die VERY YOUNG. Of course i could then say that i don't warrant diodes, and you'd have to pay for a new one when it died....


Well even as it is, i can not afford to warrant 6x diodes for a long time, they are simply too expensive! But because of the way i select them, they are VERY UNLIKELLY to die any time soon. In fact, they will most likelly last you a year, if not YEARS of normal use!

For example, i have not yet lost a single high efficiency 6x dode, even tho they produce more power at the same current than others. Even good normal diodes don't die just like that.


That's also why i can give a birth-defect warranty on them, in case one should die WAY TOO FAST...


AGAIN: While i can't afford to give a longer warranty on 6x diodes, due to their cost, they are EXTREMELLY UNLIKELLY to die any time soon, due to the way i select them!



But all this careful pre-testing on my Diode Analyzer, collecting the full P/I/V data for every single diode takes a lot of time!

And that, on top of the fact that i can't use all diodes due to the very low efficiency of some, is the other part of the reason why my lasers cost more...


However, while i can reduce the cost of a build by using ready-made drivers, i don't want to stop pre-testing diodes!

I've been getting too good results this way to stop it now!



But that's a good thing! Because my base price for a GGW 6x laser guarantees you get AT LEAST a good normal-efficiency diode, which will produce a decent power at a current under 200mA AND in most cases last you a year if not several with normal use!

ASK FOR MORE INFO AND EXPLANATIONS.... (EMAIL PREFERRED)


I have not yet set a single 6x laser to a current above 200mA (except my own experimental ones), but i have made a large number of 6x lasers with powers above 210mW, simply through careful diode pre-selection. And they all still work! These lasers go over 250mW with glass lenses.



An additional benefit of my diode pre-testing is, that if you want, you can request a freak (more power at same current due to higher efficiency) or a high wavelength diode (brighter looking at same power), or if you REALLY want, even a high wavelength freak (higher power AND brighter looking), but they will cost a little more, depending on how rare they are (simple statistics)..

It was always my belief, that higher efficiency diodes have a better, more perfect crystal with less imperfections, and the tests i did comparing low vs. high efficiency 6x's now seem to confirm this. So a higher efficiency diode can most likelly be used to produce more power with a longer life, if the current is not higher.




There is a way to save money through this too, if you were to request a lower efficiency diode... It too can be set to a high power, if a higher current is used, or left at a slightly lower power at the same current.....

But keep in mind, that it is possible, that a low efficiency diode will have a shorter life - the lower efficiency COULD be a sign of imperfections in the die...


That's why i normally never use the VERY LOW efficiency diodes, like those that peak at only 140-169mW at the 200mA pre-test - imperfections in the die make a diode burn out faster.




Instead i set those to powers even a PHR would survive, like 120-130mW, and cycle them to see how long they make it, to figure out what is wrong with them.

Ok, i'm going to Ljubljana for the weekend yet again. Probably won't be able to check my emails or PMs till i'm back, cos i'll be helping my GF move to a new place...



I'm taking the lasers i finished this week to the post office on my way. ;)
I'll contact the soon happy new owners, when i get back on Monday. :yh:

"Eventually" MIGHT be too late. Or not...


But the Chinese are already threathening with a low stock at the very beginning. Now they did this with GGWs from the start as well, but they do so to keep the price up.

But in this case there may actually be less available.... With the 6x's i made myself a very big stock from the start. Here they are not even offering a small part of that.



That's why i said that for upgrades i'd need people to order WITH me, but from another source, since mine is already fully exhausted with the 10 i'm getting... At least that's what they say. Altho they might offer another 10 after this order.. They are always trying to squeeze me for all i'm worth, and sell 100 PHRs or LPCs on top!



But if you ordered a sled from Kendall for example, you'd have an upgrade safelly reserved.

However i don't recommend doing so until i cycle the test diode he is sending me to death, and make sure it can deliver the high powers with a decent enough lifetime....

my goodness i feel like such a noob (well certainly look and am one since i JUST registered on this site hours ago)

however, like any other veteran of a forum and seeing the noob asking the same stupid questions..
i saved you guys the misery but spending the past 2 days or so reading.. and reading... and omg reading threads.. even going thru old ones, and even reading all 74 pages of this thread. :eek:

finding the.. and obviously noting the big forum contributors.. from jayrob (which is how i came to find out about you IgorT).. to DarkLasers... yea.. tons of stuff.

i guess you can say my wallet's about to get a bit bulimic... and still looking around for that nice purchase.. :whistle:

looking forward to doin' business with ya guys

Hi Shogoki, just make sure you get the right kind of battery or ask him for it if you do decided to go with IgorT's laser.

oh i certainly will.. i read about your little incident. :p

hmm.. read about 8x.. and 400mW... too.. err... well that'd be sweet as my "coming back into the laser community" gift to myself... ugh.. :tired:
2am here and i'm still reading the forums..

Re: FS: >120mW PHR, 170-210mW 6x & NEW 8x Blu-Rays!!

....Otherwise, i sent Franco two lasers. The 265mW BluRay, and a 320mW Long Closed Can red..

The red is an experimental "diode-killer" laser, that for some strange reason doesn't want to die. While it's putting out more power than i ever had a red put out before! Interestingly, it is also in a v3 All-In-One Heatsink/Module...

Oh, well, finally I got them! It has taken a lot of time, probably due to the fact that August is the "summer vacation time", and Italian Postal Service has suffered of a manpower lack....

BTW, this is the famous IgorT 6x BR equipped with the "MEDIUM LENS"!!!!
Wow, it's the unique IgorT medium lens prototype actually installed on a BR laser.....:D

I promised to Igor to NOT remove it from the laser, so the test I have done is only relevant to the shape of the beam; unfortunately, for the upmentioned "summer vacation time" the lens coming from LarryDFW is not yet arrived at my Post Office.....it's a pity, as my comparison is not complete. Anyway, as I'll show you herebelow, it's not a big problem.

For the first thing I checked the P.O. of the 6x: here are some (three) pictures showing the Medium Lens and the 6x P.O.: as this value was not so clear in the wider pict, I have added a particular after the laser shut down...

3844677043_fd1b7c52c8_b.jpg


Yea, I know, Igor said this 6x output is 265mW, but I have noticed that after the "dressing" upgrade, Jerry has set my LaserBee I De Luxe to be a little "stingy" in the readings...:yh:

Well, let's go to the "beam shape" test: to carry out this test, in comparison with the IgorT 6x I have used my old IgorT PHR, equipped with the 405-G-1 lens (one of the first Jay handmade products): that to this lens my 120mW (with an Aixiz acrylic open back lens) now are 150mW!

First I started to project both the beams properly unfocused to have the same height, but I noticed that the picture was not showing exactly all the shape, so I decided to "sacrifice" one sheet of the Glow For It green phosphorescent paper, so i traced on it some rectangles to help in the comparison.

After having centered the beam, I lighted the laser and at the same time I started the "10 seconds" delay countdown of the camera: 2 seconds before the picture shot (the warning sound signal accelerates) I put a hard thick black paper in front of the laser, so to take a picture of the single phosphorescence, without moving the laser on the support: hereunder are the results!

3844848215_b784cf16d8_b.jpg


As you can see, the 405-G-1 lens show a wider flat beam in respect to the IgorT medium lens: both of the lenses show some light "ghosts", a little less pronunciated for the IgorT lens and a little more pronunciated for the 405-G-1 lens: both the lenses are good, they implement a lot the P.O. of the laser, in comparison to the Aixiz acrylic one, so it is just a choice of who loves to have a better rounded beam or who doesn't care for it.
When I'll receive the Larry DFW lens, I'll perform the test using the green traced phosphorescent sheet, so to guarantee the same references.

This test is complementary to the very good and complete test already performed by Flaminpyro:

relevant to the P.O. differences between the various lenses...

Very nice FrancoRob, thanks for the comparison! It illustrates to everyone the difference IgorT was talking about in spot shape and size... Regards, Mihnea

Good job FrancoRob...

Did you get a chance to take some comparison pictures in the same manner with the dots in focus?

Because the 405-G-1 glass lens will show even more, (or much less) of the oval pattern you captured, depending on focus...

It looks like, from how bright the center area is, that the IgorT medium lens is in better focus.
Jay

Edit: But the biggest thing, is that these are two different diodes here... (PHR vs GGW)

Hi Jay, both beams have been put out of focus in the same way, as the distance between the laser and the phosphorescent sheet was exactly the same for both; you have to think that there is a big difference in P.O.: my PHR with your lens is putting out 150mW, while IgorT 6x is a 260mW; then, if you add that the mW output of your lens are spread on a bigger surface, this is the reason why the IgorT beam looks brighter (the phosphorescent material of the sheet absorbed more mW for the same exposition time). Last, it can be that the IgorT lens concentrate the beam slightly different from yours (also if I have some doubts on this last point).:yh:
If I put the dot in focus it becomes a so thin point that's really difficult to see any difference....

The difference in brightness of the borders may also be due to a different positioning of the IgorT lens inside the lens nut; as I said before, I couldn't remove it from the laser (I promised to Igor)....
