The Fabry-Perot cavity acts a bit like a leaky bucket – it stores a lot of optical energy at resonant wavelengths as the light bounces back and forth between the mirrors, but the light leaks

A laser generally requires a laser resonator (or laser cavity), in which the laser radiation can circulate and pass a gain medium which compensates the optical power losses.
