So would i, but what would be the real world application for such a diode?
We mostly get diodes because industry has a reason to produce them - for dvd or blue ray drives, for projectors and such consumer goods.
Yellow lasers could be useful in projectors if they are efficient, and only once we get to the point projectors with laser sources for blue, green AND red are standard. Yellow could be used to get better white brightness if blue remains the cheapest color to install with a decent amout of power.
Don't hold your breath on this one, i guess

As far as these particular ones in the article go, they're by far some of the most expensive diode types currently around to manufacture, so definitely don't hold your breath for the commercial version.
Initial cost rarely says much about the eventual cost and availability. I remember blue leds being ridicioulsy expensive and apparently hard to manufacture, but 10-15 years later they were as common as the dim red ones used to be, and about as cheap too.
Perhaps these additional colors will make in into projectors to give a wider gamut, or higher intensity for yellows overal. Since cyan lasers are becoming more available as it is, there could be solutions with 5 diodes for better color rendition. I think splitting blue into cyan and 'royal blue' would be the more impressive change, but if a pure yellow instead of blended red and green could be feasibly added, why not.
Such technology would probably be introduced first in display panels, but one the consumer expectation is there from those, they could find their way into projectors quickly, especially with th newer wide-gamut standards coming onto the market.
indeed. market drives the technology. but if it remains only in stuff like medical, it'll be like 488 diodes or UV diodes for example and won't likely come down to hobbyist level price points. plenty of yellow and orange lasers exist, but none of them are really at hobby market price points in any kind of useful quality science-wise. Diode lasers have (generally speaking) crap beam quality with few exceptions unless they have very expensive construction behind them.
