On the 599nm to 605nm direct diodes, there is nothing it that article about temperature. I suspect, but don't know, that these are well below ambient temperatures.
developed an LD that intrinsically emits in the yellow-orange spectral range from 599 to 605 nm wavelengths at room temperature in a laboratory environment.
This was rolled out 22 months ago. Who exactly has any 599nm to 605nm direct diodes available? And they are still orange, not yellow. I would be among the happiest here to see some orange direct diodes. Would be even happier to see some real yellow ones. Even if they cost $10,000 each it would be a huge accomplishment. But, I've been reading about yellow direct diodes for years only to be disappointed year after year.A total of 0.8 W optical output power in pulsed mode operation was realized for a laser with a 1 mm cavity length and 50 µm stripe width, being limited by the catastrophic optical damage of unpassivated uncoated mirrors.
