The problem is not just managing the power and resultant dissipation. Even apparently “negligible” resistances in the source-load path have become major impediments to effective power delivery due to basic I 2 R losses: at 200 A, just 1 mΩ of lead/trace resistance is a 0.2 V IR drop and 40 W dissipation. Further, using smaller converters

Silicon Windows - Zygo Corporation - Home Page

Silicon windows have good transmission in the range from 1.2 to 7.0 µm, with little or no distortion of the transmitted signal. Silicon has an advantage over other IR materials due to its low density (about half that of Zinc Selenide or Germanium), making it ideal for optical systems where weight is a significant factor.
