High Power Blu Ray sleds

[FrothyChimp]

Can anyone tell me which optical sleds have the highest power Blu Ray diodes? And then maybe the next few that fall into the high power list.

I see a lot of discussion about this sled or that sled but I'd like to see a definitive list from high to low for output. Not being a Blu Ray expert (yes I can admit that) I think it would help not only me but anyone else looking to build one.

Furthermore, it is my philosophy that if something is worth doing, it is worth overdoing, so if I'm going to build a 405nm laser I want to push the envelope.

I'd like to see that as well. 803T, or the other numbered sleds I read about don't mean squat to me, unfortunately. phoenix77/rob

It seems that the 6x blu-ray burner drives are the top diodes, with some people pushing them close to 200 mw(dont quote me on that).
Next comes the PHR-803t which are the most popular due to their cheap price and strong power output(~80mw depending on current).
Then there are the ps3 diodes which are like around 10mw.

The 6x are fairly uncommon because its $300 to buy the drive to extract the diode from. The PHR-803t has a lot of testing going on currently to find what it can be pushed to safely, so more info will come with time. And I dont know much about the ps3 diode... I think everyone has abanded that for the 803t.

The DT0811 sled falls in between the 803T and the PS3 sled.

The 803T blu-ray diode can be safely pushed to 100mw@~125mA, the DT0811 seemingly to 80mW@~125mA w/minor heatsinking.

6X diode -- (I don't know the sled number for this one) 190mA = 200mW

PHR-803T -- input/output still in research -- Most running about 100mA = 90mW -- (I'm running these at 177mA = 145mW)

DT-0811 -- input/output still in research -- Most running 100mA = 80mW

KES-410A -- 38mA = 20mW

Peace,

Good job there Dave! Just to add the model for the drive to get for the 6 X. Made by LG.

Model number GGW-H20L. - $275 bucks.

The 803T - $25 to $30 bucks. I think it is safe to say that the 803T is the one to go for!

HIgh power?

Two I'm aware of, already covered above.

the '6x' diode is ripped out of the LG - super multi blue (GGW-H20 L) drive. It's apparently good for ~200mW (give or take 50mW), based on the extensive empirical testing of other members here. These drives are $200-300 I believe. I'm not certain if the diode has been identified.

The other is from the 803t sled. These drives flooded the market with the demise of the HD format. Can be had for $20-50. The diode is likely Toshiba - it may be this diode:

(as identified by heruursciences, in this thread:http://www.laserpointerforums.com/forums/YaBB.pl?num=1213678915)
This diode is probably good for 100mW, +/- 20mW.

If the above is indeed the identity of the diode, note this part is going for > $1000 at digikey.

the 803T from my testing can put out a lot more than 100mW. I don't know the max or how safe it is to push them that high but I am getting much higher than 100mW. I need to do some more testing before I say exactly what it is putting out cause I feel that maybe the power meter was not calibrated correctly. I know I have gotten at least 130mW out of one, but that one is fully TEC temperature controlled. I would NOT recommend pushing them any farther than 120mA in a good heatsink for now. My opinion as of now until I take more data is that 120mA is the max safe current. The 6X from the LG burner is still going to be the highest power for a while. If you want a lot of power, go with one of those.

How long are letting that one burn at a time?

Peace,

Oooooooo ---- 888 ------ is that better or worse than 666 ?

Not very. I'm just taking quick measurements for mode stability right now so I switch currents a lot. The long term diode is running at a smooth non-heatsinked 120mA now though.

So 120mA, stock heat sink, 100% duty cycle on the "long term" test?

yup, and it's under a little shield made of paper so people walking by wont get blinded, no airflow. These diodes are proving quite robust. i want another 10 of them at least

I just turned my 6x up to about 180mA tonight (may go just over 180) and i'm now hitting 200mW on my power meter. 190mW just wasn't cutting it for me  ;D

I've pushed the DT0811 to currents in excess of 140mA for short periods, but I really only had one to play with so i cant give any solid data on that diode. I think I may be buying some $10 broken HD-DVD xbox drives from ebay here soon, so maybe I'll get a few more.

I thought I would also add, the 6x drive is only $259 on newegg right now. So you figure, $259 + another 60ish dollars for a driver and host and you've got yourself a 200mW 405nm laser for around $320. I'm really surprised more people haven't done it. Considering the power to price ratio.... and the color!

hey when are we going to start a lasers anonymous
where did that come from ????? : : : : : : :
