I was so excited for this to be real and to buy one....

Other QD emissions devices are a bit broad on wavelength spectra, I would expect this to be limited in frequency by the manufacturing precision of the QD geometry and material consistency.

Maybe they will be the way forward in my quest to make an orange laser
It’s an interesting thought. It looks like if you can control the size of the dots then you can control the wavelength. However I think the challenge will be how do you make the dots the right size with a diy setup.
