I've followed this topic for a few months.
From December:
Mitsubishi Electric launching record 2.1W-output 639nm red laser for projectors
Another site:
ML562G85 - Mitsubishi | Laser Diode
Here is even info that is single emiter, but, it can be mistake.
Datasheet...
On February Mitsubishi launched a new powerful red diode ML562G85, but datasheets are poor. There is no information about structure - single emiter or not. If it's single, it will be a revolution in red lasers. Do you have some info about it?
