Note that both the local amplitude and the spacing of the wavefronts vary to some extent. The wavefronts are formed as above, and the beam quality is still very high, but the amplitude and phase of the beam varies along the propagation direction. from the left side) with perfect spatial and temporal coherence.įigure 3 shows a beam with high spatial coherence, but poor temporal coherence.
