Frequency fluctuation effects general
$$ \frac{\Delta f}{f} = - \frac{\Delta L}{L} - \frac{\Delta n}{n} +\delta_{lock}$$
| Effects of fluctuation | Part of fluctuation | Reduction of effect | Measurement method |
|---|---|---|---|
| Vibration | $$ \frac{\Delta L}{L} $$ | stable mounting design & passive/active vibration isolation | |
| Temperature | thermal isolation from environment: temperature stabilized vacuum chamber & heat shields | ||
| Acustic | acoustic isolation box & vacuum chamber | ||
| Intensity | intensity stabilization | ||
| Vacuum | $$ \frac{\Delta n}{n} $$ | low pressure & stable pressure | |
| Lock PDH | $$ \delta_{lock} $$ | temperature stabilization of EOM & using Glan thompson polarizer | |
| Lock RAM | |||
