Quote:

I used the result from [1] to calculate frequency noise from thermoelastic and thermorefractive due to RIN.

at 10 Hz, it is about 1.4mHz/rtHz. RIN at 10 Hz used here is 10^-4.

This calculation does not include power fluctuation from RFAM/ pointing stability.

The result will be compared with a simulation from COMSOL (in progress.)
