Blu-Ray Writer Harvest

Hi, has anybody else tried a blu-ray diode from the Sony 2 X writer? The drive model is BWU-100A. I had to connect it like this before it would work:

Here's a graph of 9 current readings I have plotted so far. Readings were taken with an LPM-1 at 473nm X 1.75 using a Meredith acrylic lens. Notice that it started getting 'steeper' again after 95mA's. About 3mW's gained per every 5mA's current. Think I should go higher?

My main question is, does anybody know if I can go ahead and connect my heatsink/LD case to the MXDL body? I am using an LM317 driver, so the negative side of the battery is connected to the host/heatsink/LD case. I got a 4.6 voltage reading between the leads. I also got a 2.84 voltage reading between the positive lead and the LD case. No voltage reading between the negative lead and the LD case.

Please help if you know anybody who has worked with this diode!

Well, just to let you guys know, after I saw how HOT that 4/6 X diode that drlava has (Hemlock Mike too), I figured...'if I kill this one, it will be a good excuse to get that drive'! So, I went ahead and went with my gut instinct, and connected the heatsink/LD to the MXDL case! I even checked it with an ohms meter to make sure it had a good contact before I turned it on! Lol.

I am happy to report, that it works just fine. The mW reading was the same, whether the heatsink was connected to the MXDL case, or not...

P.S. For a comparison between the my PS3 blu-ray @ 16.7mW's vs my BWU-100A blu-ray @ 43.2mW's, here they are together...
