optmat.solid.raman_response_validation

Fused silica’s Raman responses against measurements (TC-693, TC-694).

As optmat.gas.raman_response_validation, for optmat.solid.raman_response:

• silica_gains(): the absolute Raman gain of fused quartz (Stolen & Ippen 1973), for each model with its own f_R and optmat’s long-pulse n2;

• silica_low_frequency_gain(): the shape of the gain below 25 cm^-1 (Stolen et al. 1989’s Eq. (10));

• silica_raman_fractions(): the nuclear share of the long-pulse n2 from spontaneous Raman spectra (Hellwarth, Cherlow & Yang 1975), against each model’s f_R.

Functions

silica_gains()	Return fused quartz's measured Raman gain against each silica model's.
silica_low_frequency_gain()	Return silica's gain below 25 cm^-1 against Stolen et al. 1989's Eq.
silica_raman_fractions()	Return the nuclear share of silica's long-pulse n2 against each model's f_R.

optmat.solid.raman_response_validation.silica_gains()

Return fused quartz’s measured Raman gain against each silica model’s.

Stolen & Ippen 1973: pump 526.0 nm, Stokes shift 330 cm^-1; each model with its own f_R and optmat’s long-pulse n2 at the pump (the Kerr fit, TC-393).

Returns:

list of ResponseComparison

Per model (cm/W).

optmat.solid.raman_response_validation.silica_low_frequency_gain()

Return silica’s gain below 25 cm^-1 against Stolen et al. 1989’s Eq. (10).

The gain normalised to its maximum (near 440 cm^-1), a Omega + b Omega^3 with Omega in cm^-1 (stolen_1989/low_frequency_gain).

Returns:

list of ResponseComparison

Per model and shift (dimensionless).

optmat.solid.raman_response_validation.silica_raman_fractions()
