Cooling requirements

Series 48 electronics are mounted opposite the laser tube in the smaller section of the “H” bay and share

the same cooling removal as the plasma tube. Typical efficiency of CO

laser plasma tubes operating in a

TEM

mode is 10% to 12% (radiation out to RF power in). Factor in the conversion efficiency of AC

input to RF output and the overall “wall plug” efficiency of these lasers drops to about 6% to 8%,

resulting in a considerable amount of heat removal, even at 10 W and 25 W output power levels;

therefore, external cooling in the form of forced air- or water-cooling is required.
