"They work by focusing sunlight onto crystalline materials, such as
Neodymium-doped Yttrium-Aluminum-Garnet..."

I don't see any problem with modifying the system to use an independent solar
collector connected with Fibre-optic cables.  There are already collectors like
that used for providing natural light during the day to indoor spaces, and I've
read that the light in the cable is so intense that it can start fires if
connected improperly.
