DEFINITION

Classification: 505/180

Device producing stimulated emission (e.g., laser, maser, etc.):

(under subclass 150) Device that utilizes a superconducting component to excite the oscillations of particles, or atoms or molecules between energy levels for generating coherent electromagnetic radiation in the ultraviolet, visible, infrared, or microwave region of the spectra.
