resonating cavity

[′rez·ən‚ād·iŋ ′kav·əd·ē]
(electromagnetism)
Short piece of waveguide of adjustable length, terminated at either or both ends by a metal piston, an iris diaphragm, or some other wave-reflecting device; it is used as a filter, as a means of coupling between guides of different diameters, and as impedance networks corresponding to those used in radio circuits.

Unlike conventional gas lasers, a fiber laser uses part of the fiber as the resonating cavity where the laser action takes place to generate laser beams.
This eliminates the need for a resonating cavity and permits the cell size to be reduced to below the wavelength of the microwave radiation.
