Ah, thats what you were refuring to!  

The solar pumped laser works by using the sun light to excite a lasing medium
that then lases in a visible light frequency.  Unfortunatly I think most of
he energy is lost as wast heat.  Given the amount of power were talking
about, that could fry a lot of lasers.
