Deotare et al. used one-dimensional photonic crystal mirrors to create a region with an "ultra- high" value of this quantity. The rate of spontaneous emission is proportional to wavelength cubed times this quantity divided by the mode volume, according to the Purcell effect. Cobalt- doped zinc selenide and cobalt-doped spinel crystals are used in saturable absorbers which modulate this quantity in a "passive" manner. This quantity is used to measure the selectivity ofa band-pass filter. On a graph of power vs frequency, this quantity equals the frequency at the peak divided by the width of the peak. This quantity equals the resonant frequency times the inductance divided by the resistance for a series RLC circuit. For 10 points, name this quantity, the ratio of the energy stored in an oscillator to the energy dissipated in one cycle, thus quantifying the degree to which the oscillation is damped.
