  Increasing the area of an object's surface seems like an easy way to
  increase its heat transfer to its surroundings.  This might help alot
  in bringing an objective to thermal equilibrium.
  
  Has anyone pursued this idea?  >>
 
 About 10 years gos a Stanford research group was able to pull
 1000 Watts out of a 1" square piece of silicon by etching deep
 groves ont he back side of the wafer and using water as a cooling 
 fluid. COntrast this with the 25 Watts that a normal chip could
 disipate through regular packaging techniques.
 
 So the idea works.
 
 But groving the back side of a mirror is bound to interact with
 the stiffness of the mirror itself, and may require a more exotic
 mount to maintain sruface accuracy.
