In astronomy, laser frequency combs are horribly expensive (~$0.5M), but fantastic for calibrating high precision spectrographs. It would be interesting to see if this method could be tuned for that application (namely, shifting to the visible), such to enable cheaper spectrographs.
How would you modulate the individual wavelengths, considering they all come from the same source ?
I had, maybe naively assumed that laser diodes were switched on/off electronically to modulate a signal. With this laser you’d have to modulate after the light source somehow ?

You can always filter the frequencies you don’t need
The question remains: how to modulate individual wavelengths.
could you use this in show lasers? currently they use RGB mixing with electro-acoustical crystals for intensity modulation.
This seems like the kind of technology that will quietly revolutionize a lot of things in 10 years when manufacturing is figured out.
