WebbA 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. Exceptions are a few cases … WebbSince the Rayleigh range (see Equation 2) depends on the spot size w 0, it is clear that the cavity spot size depends on the ratio between the mirror curvature and the cavity …
