The study indicates that the intensity-dependent phase of the atomic dipole should play a major role in the spatialcoherence proper ties of harmonic emission. This breaks the spatialcoherence of the laser beam and produces a smooth intensity profile. The generated beam is linearly polarized and possesses high degree of spatialcoherence. Second, activity was quite uniform across the activity distribution as indicated by a remarkable spatialcoherence of activity. Spatialcoherence measurements and x-ray holographic imaging using a laser-generated plasma x-ray source in the water window spectral region. As expected, the harmonic beam presents a relatively high spatialcoherence. Thus, high spatialcoherence may be achieved by using a source having a small size or by observing the beam at a large distance from the source. Rood's velocity measurements, on a cylindrical protuberance with a 3 :2 semi-elliptic nose, show extensive spatialcoherence in the vortex flow downstream of the protuberance a t low frequencies. While spatialcoherence is related to the beam divergence of the laser, spectral coherence is evaluated by measuring the laser linewidth of the radiation.

Spatialcoherence is typically expressed through the output being a narrow beam which is diffraction-limited, often a so-called pencil beam.

Spatialcoherence allows a laser to be focused to a tight spot, enabling applications like laser cutting and lithography.

Spatialcoherence of laser beams also manifests itself as speckle patterns and diffraction fringes seen at the edges of shadow.

Rotating diffuserswhich destroys the spatialcoherence of the laser lightcan also be used to reduce the speckle.

Spatialcoherence also allows a laser beam to stay narrow over long distances (collimation), enabling applications such as laser pointers. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. High harmonic generation strongly depends on the driving laser field and as a result the harmonics have similar temporal and spatialcoherence properties. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Two of the most distinctive characteristics of laser emission are spatialcoherence and spectral coherence.
