Spaceborne containerless materials processing will require efficient heating systems. The technique described here makes use of lamp systems with power conversion efficiencies that are as high as 65 percent. The effectiveness of these systems is enhanced by multipassing the lamp beam to re-use the lamp flux that is not absorbed by the sample on the initial pass. We believe that these systems have a great deal of merit when compared with more conventional tungsten furnaces or laser systems. We have evaluated the effectiveness of an optical multipass radiation system, OMRS, used in conjunction with a high intensity light source as a means of heating levitated samples.
