Blue laser in CDP?

I thought that one of the YBA players and perhaps the Classe omega player used blue lasers. I may be totally wrong on that though. There were a lot of technical papers written a few years ago (one of my profs was doing lots of research in blue lasers) and basically there seemed to be no real benefit over red for CD reading.

My Electrocompaniet EMC-1 MK II emits a blue light inside the cd transport while playing, but I don't know if it's from a blue laser.

Yes, YBA cd players - CD integra, CD3, CD2 and their flapship CD1 are all using blue laser but comes with only 18bit converter.

It's not blue laser but a blue led place near the reading laser.
