A Question about stimulated Raman emission

Click For Summary
Stimulated Raman emission involves the interaction between light and phonons, where the damping of the phonon field is significantly higher than that of the optical Stokes field. This concept is not commonly addressed in many materials, leading to confusion among readers. The inquiry seeks an intuitive explanation of this phenomenon, particularly in relation to the referenced paper. Understanding the differences in damping rates is crucial for grasping the mechanics of stimulated Raman emission. Clarifying these concepts can enhance comprehension of the underlying physics involved.

TL;DR
How is that Stimulated Raman emission relies on damping of the phonon field that is much greater than for that of the optical Stokes field?
I have read a paper states that "Stimulated Raman emission relies on damping of the phonon field that is much greater than for that of the optical Stokes field". But I cannot understand this, since all the materials I read do not state this. Can anyone explain it intuitively?

Thread 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
