Query: The influence of phonon harmonicity on spectrally pure resonant Stokes
  fields   Thanks to their highly coherent emission and compact form factor, single
axial mode diamond Raman lasers have been identified as a valuable asset for
applications including integrated quantum technology, high resolution
spectroscopy or coherent optical communications. While the fundamental emission
linewidth of these lasers can be Fourier limited, their thermo-optic
characteristics lead to drifts in their carrier frequency, posing important
challenges for applications requiring ultra-stable emission. We propose here a
method for measuring accurately the temperature-dependent index of refraction
of diamond by employing standing Stokes waves produced in a monolithic
Fabry-Perot (FP) diamond Raman resonator. Our approach takes into account the
influence of the temperature on the first-order phonon line and the average
lattice phonon frequency under intense stimulated Raman scattering (SRS)
conditions. We further utilize this model to calculate the
temperature-dependent thermo-optic coefficient and the Gruneisen parameter of
diamond in the visible spectral range. The theory is accompanied by the
demonstration of tunable Fourier-limited Stokes nanosecond pulses with a
stabilized center frequency deviation of less than <4 MHz.
