I am not understanding exactly what you are saying ILIKELASERS...
When you say blue ray, are you talking about a 405nm diode, like from a PHR, GGW, or the 8x, 10x, or 12x, bluray sleds? The Bluray diodes are actually violetish in color. Or are you meaning the a140 diode because it is not called Blue ray, just a 445nm (blue) diode.
I have definately contemplated having a 12x 405nm diode in a kryton groove, and I will once the Kryton GB is all done!!! And IIRC, at least a few members like Daguin, jayrob, Hemlock_Mike and I think kenom have had 12x diodes in Grooves or still do.
The highest power bluray (405nm) diodes now are the 12x diode from a Pioneer BDR-205 sled and the 12x diode from a Lite-On SF-BW512L Sled. Some people are thinking these might be the same, just different manufactures. And the highest power achieved so far with this type of diode, if only for a few seconds was 998mW, but usually you can get a handheld to be around 600-650mW stable. I can't remember the persons name, (I'll get back to you on that) who got to 998mW with power supply, but it popped right after. No higher power has yet been achieved with 12x 405nm diodes.
