1. A system for heating an object, comprising:
an electromagnetic radiation source configured to emit electromagnetic radiation;
a first stage including a target area, at least a first portion of the electromagnetic radiation being directed toward the first stage, the first stage being configured to direct the object and first portion of the electromagnetic radiation to the target area such that at least some of the first portion of the electromagnetic radiation strikes the object to thereby heat the object and produce particulate matter;
a second stage having a cooling fluid flowing therethrough such that the object received from the first stage moved through the second stage is cooled; and
a third stage fluidly coupled to the first stage such that air and the particulate matter flow from the first stage to the third stage, at least a second portion of the electromagnetic radiation being directed to the third stage such that at least some of the second portion of the electromagnetic radiation is configured to strike the particulate matter to thereby incinerate at least some of the particulate matter, the third stage including a filter, the third stage being configured to direct the air in the third stage through the filter and out of a vent.
