From the transmission geometry of a small-angle experiment it is obvious that the transversecoherencelengthis the key factor that determines speckle.
From theCambridge English Corpus
Therefore, we only consider the harmonics emitted within a single time-dependentcoherencelength.
From theCambridge English Corpus
At the longer wavelength, no adaptive optics are necessary, because the transversecoherencelengthparameter r0 is 360 cm, the same size as the mirror.
From theCambridge English Corpus
These unique properties provide good beam quality, high pointing stability, and largecoherencelength (a single longitudinal mode) of the output laser radiation.
From theCambridge English Corpus
Note that the transversecoherencelengthdoes not depend on the wavelength spread but only on the geometry (source size and distance source object).
From theCambridge English Corpus
Any light that is outside the shortcoherencelengthwill not interfere.
