Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

there are 2 Canned diodes, and one of those weird looking SMD like Diodes.

I can only spot two diodes. The flat SMD things in the green circles are photodetectors. Because there are two separate light paths, there are two detectors.

And what about those trapezoid optics people keep talking about? I can't spot any. Ok, there is an optic in there with a trapeziod shape but the shape is irrelevant to its function, as it is a plain simple dichro front surface mirror (pink circle).

Tere is however one obscured optic. I can see two blobs of glue extending from beneith the PCB and there is a ribbon cable going toward it. (yellow circle) It can't possibly be a diode though because the ribbon cable has two thin unshielded lines on it.

I have seen those ebay sleds, when Glenn showed me a link once... I remembered the writing on the diode. The letters and numbers. These sleds reminded me of something, but i couldn't figure out what..

These diodes don't have that same writing, so they are likelly different. But if those are only readers, there is not much chance off these being writers, since they are using the same sled.

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Igor My diode has been running 200mW for over 60 hours now... I think you are mistaken... You are under-estimating these babies.

I am not underestimating the 4x diodes. I believe that the 4x's are the best 405nm diode available at a reasonable price so far!

I think the 4x's are actually capable of sustained continuous 105mW output. Possibly even a little more, perhaps the 4x's could even provide 120-130mW through an acrylic lens with a long life, much unlike......

These are much more powerful than the PHR's. also, remember, PHR's were 2.4x, these are 4x...

......PHRs.  The 4x writers are most definitelly WAY more powerful than 2.4x readers... It's the PHRs that are overestimated to a bizzare level, not the 4x's that are underestimated.

A PHR, when put through the same testing (1 min ON, 1 min OFF), at the same current of 150mA, lasts only 3-20 hours. I've seen much less than 3 hours tho, in the near-20 i killed before making the cycler circuit. I have never seen more than 15-20 hours in a PHR at >150mA. There is this one PHR with a question mark above it, but the clock is still ticking. All the others are dead.



BTW, an update on the test 4x:
Last night it was putting out between 125-135mW depending on how kinky it felt. I woke up this morning, and my 4x was dead. It survived somewhere over 130 hours or so at 150mA. Need to check the counter, to see exactly how long.

It degraded, dropped in it's own kink and this morning it was dead. Had i set it bellow the first kink it would probably have survived a long time.

Kage lost two before reaching 140mW. They may not have the same short lived fake toughness of the PHRs, but i think that at <120mW, they would be WAY more reliable than PHRs at the same power. The 4x i tested at 150mA lived longer than any PHR i have ever seen at the same current. And i've seen many! I just hope my other 4x's are also this good, and that this wasn't a random super-tough freak!

Because i know one thing for sure. The 4x i sacrificed for testing is without a doubt the best 405nm diode, i have seen so far, with the exclusion of my 6x of course.


What i don't understand is, how your 4x could possibly have been running for 60 hours? You have it in a laser. I had my test 4x on a circuit, that has been turning it on for one minute and and off for one minute almost since the moment i got it, day and night. I later reduced the OFF-time a little, to speed up the testing, and i only got to around double what you're saying.

I think you're overestimating the time you had it ON. Even a 6x may not have survived 60 hours of 200mA. My 6x degraded at 198mA in less time than that. And i sped up the degradation in anticipation of the "6x" GB, by setting it to 219mA. It's dying.

The 6x may survive 200mA for a certain time. But not without degrading and eventually dying a premature death. It's our expectations, that are too high.


I wish 4x's were still available, beause they seem to be good diodes.

Woah i through phr would last a while at 150mW. Any test on the 12x?

 

[Zom-B]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

lol you beat me to it again igor. Although I must say your entire description sounds exactly like PHR-803T diodes, and for those the figures are a bit optimistic. So far, I have one that set in the middle third tier (after the second kink) died after 78 minutes (162mW), and one set at the end of the first tier (just before the first kink) died after 250 minutes (189mW(!)). The latter had a very high first kink starting at 198mA. Currently I have another PHR set to the beginning of the third tier and use it with an adjustable lab driver and only use that power when I need it. (a tier is the straight range where no mode shifting takes place)

I also just discovered and refined the method of finding kinks by looking at the mode shifting (technically it's not hopping). You should look very carefully at the spot though (preferably on a fluorescing surface like paper) because the start of a mode shift is very slow and almost not even visible. Further into the mode shift, are the shifts faster and more obvious. See Re: PHR-803T batch testing.. Windowless 803Ts?

Furthermore you imply that the readers know the direction in which the kinks move with temperature (even if it doesn't matter when your directions are exactly followed), so here are the facts: When the laser is cold, the kink is lower than when the laser is warm (and it emits more mW). When the laser is cold, the wavelength is longer than when it is warm because at higher mW, the wavelength is longer.

Correction, I just remembered my 198mA/189mW PHR died while changing hosts (window shattered). The 250 minute diode must have been another. *looking through spreadsheet*. Yes, it was another one at 170mA/166mW, but too set at the end of the first tier. It degraded from 166W to 150mW and stayed there until it just went dark.

I don't know how long the 189mW PHR lived because I did not have on-time recorders yet, but i know it didn't degrade, and I think I used it at least as long as the 166mW one, probably 1.5 times as long. (>5 hr?). It was also NOT EVEN set at the end of the first tier because I didn't dare to go higher at that point in my life (it was my fourth PHR ever and I never had one that strong since, and I have bought 22 PHRs since. Wee. I want haz a 189mW PHR again :'()

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

BTW, Igor, How did you speak to "the supplier" when You have no idea who he is   ?? This guy is a personal acquaintance of mine, and apart from me, he does not do much external business.

I did not say i talked to your guy. I talked to the supplier, of the SF-AD112 sleds.

I fear, that your guy went browsing and found "Sanyo announces 12x Blu Ray", and jumped to conclusions, like we have.


I talked to the same supplier i talked to, when researching how it came to the idea, that 4x's are the same as 6x's. They told me a customer sent them a picture of a 6x sled, and based on that picture they decided it's the same. But i explained why the diode can't be the same if the sled is...

Maybe your guy is the customer, who sent them the 6x picture?

could be..


Thank you very much for clearing up the cofuzzlation about the PHR/4x. Yes, when I say 60, its a little exaggerated, and a guesstimate, I haven't been measuring exactly, but I have been using it for about 2 mins on/4mins off for a little while. Maybe mine is a freak? I have no idea...

Should I try doing what you did, take it out of the laser, put on a heatsink, and measure/graph it at sustained times?

If there's a GB round-4, sign me up for one unit.

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Let's test this strange new diode and see what happens....

It's not likelly to be any kind of writer, but it could still be better than the PHR. At least it's not the same as in the ebay sleds.

 

[Kage]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Would it be fair to say that the 4x is likely to give us around 10x the life expectancy at powers we could already achieve with the PHR, but not necessarily more power than the PHR? I'm thinking it is not really worth replacing a PHR with a 4x in an existing project unless the PHR actually dies first.

And if the above is true, if we are being offered diodes now that are less than the 4x, are they not awfully expensive?

 

[IgorT]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

From what i've seen, and from your and other's test reports, i almost have a feeling, that at a reasonable power the 4x would outlive a PHR, but at higher powers, they die almost at the same rate?

It doesn't make much sense, but the fact that PHRs can survive really high powers even for a short time doesn't make much sense either! And yet they can live long enough to fool you into believing they will make it. My one and only personal PHR just popped last night, when it was really cold..

It's as if the 4x was more like a "normal" diode. If you power it just right, it would live for a long time, but if you go a bit too high, it's suddenly over. With PHRs, the life just exponentially gets shorter.... PHRs are really strange diodes.. They shouldn't allow us to do what we do to them. But they do. Looks like all 405nm's share this trait partially, but the extent would seem to vary..

I would love to do some higher power aging tests, but i can't afford it now with the supply being over.


If 4x's were still available, i would gladly buy more of them...


I REALLY think we NEED to press for 6x's!

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Hey Igor, how is your 6x doing anyway? I haven't asked you about it in a while

 

[IgorT]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Hey Igor, how is your 6x doing anyway? I haven't asked you about it in a while  

Hey Jason!

Well, it's still my best diode. Multiple PHRs died at lower powers in the same time as my 6x kept living.

But it degraded a little, even at 197.8mA... Remember, i'm a heavy user, so i notice this sooner than most (i even lase in my slep  ;D)...
I told you it's "losing mW's" a while ago... Well, i set it to 219mA in anticipation of the "6x" GB, in order to speed up the degradation, to see if it was really happening, and to learn what to set the GB 6x's to. Well, unfortunatelly it worked - the degradation part at least.. It started out at 213mW plastic/262mW good custom lens, later it dropped to 208-209mW...

Now that there is nothing to replace it with i turned it down to 197.5mA, where it surprisingly still does 187mW/230mW! So it's not as dead as i feared! It was at the same power before i turned it up.

I really hope it will outlive many more PHRs. At this moment it's my one and only personal blu ray (my latest PHR gave up last night at 160mA)! I would probably cry if it died.. (would you get me a new one just in case?  :)

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

Does anyone have a V-I-P for the 4x and 6x blu-ray running at higher current up to 200mA?

And can some one post pics of the 6x blu-ray sled?

 

[artix]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

So what does happen now? Your supplier ran out of GBW H10Ls...

Why don't we have a super GGW H20L GB? Like we wait >3 months and hopefully we can get 1000 of them?

 

[TheMonk]

Re: 12x Blu-ray SLEDS GB! 450mW!! Sanyo 12x!!

So is GBW-H10N and GGW-H20L using the same Lens? Yes or No? :-/

Any body :
