any system that resonates an electrical circuit that combines capacitance and inductance in such a way that a periodic electric oscillation will reach maximum amplitude a hollow chamber whose dimensions allow the resonant oscillation of electromagnetic or acoustic waves
The laser cavity, lasing medium and rod, and the two reflecting mirrors The mirrors reflect photons of light back and forth (i e , cause them to resonate), and the laser beam is amplified
Anything which resounds; specifically, a vessel in the form of a cylinder open at one end, or a hollow ball of brass with two apertures, so contrived as to greatly intensify a musical tone by its resonance
The mirrors (or reflectors) making up the laser cavity containing the laser rod or tube The mirrors reflect light back and forth to build up amplification under an external stimulus Emission is through one of them, called a coupler, which is partially transmissive
Any of various apparatus for exhibiting or utilizing the effects of resonance in connection with open circuits, as a device having an oscillating circuit which includes a helix of bare copper wire, a variable number of coils of which can be connected in circuit with a condenser and spark gap excited with an induction coil
