Solution:
A particular laser line is emitted at a very specific wavelength corresponding to one mode (light path) in the laser's cavity.
Over time this wavelength varies somewhat around a center wavelength (the amount of variation is the linewidth).
Coherence Length:
The length of time that coherence is maintained is …
