edit"Spectral purity" is not at all a well-defined concept, and certainly not as defined here. is not 'particularly important', in fact it is close to meaningless. Physicists use linewidth instead, which is much more useful.
When use in the scientific literature, "spectral purity" usually refers to the ratio of amplified spontaneous emission and/or side modes to the main laser line. — Preceding unsigned comment added by 2001:630:12:10C0:9E8E:99FF:FEE3:4FDF (talk) 16:39, 12 December 2014 (UTC)
