I'll just throw it out there as a wild idea, but what about AlBeMet  (it's a funky aluminum beryllium composite).. higher thermal conductivity than aluminum. Has a CTE that's pretty close to ceramics, Toxic as all get out if machined, but hey, maybe it might be a solution.

Why not just use a Lytron cold plate? They are used on diode laser assemblies and keep them super cool. Lytron will make a cool plate  in any configuration, the stock ones do a FB job.

Well, yes, a chiller is a decent approach, but that's a big step: from cooling based on transfer to ambient environment (heat sinks) to mechanical refrigeration.  But maybe that's what it's going to take to get the heat out of high power density devices.  For all we know, in 10-15 years, you might be able to get it all as a reliable packaged assembly, sort of like ThermoElectric coolers today.
