(under subclass 333) Subject matter wherein a beam of "free" and unbound electrons of an atom or molecule are passed through an undulator (i.e., "wiggler"), which creates a magnetic field of alternating polarity, to cause the electrons to move along a helical path (i.e., "wiggle") for the release of a high power light radiation (i.e., amplification of the light input beam).
(1) Note. The use of a free-electron laser for light amplificatoin belongs in this subclass.
