\section{Conclusion} \label{sec:conclusion}
    
We have shown that the noise of an interferometric system can be reduced significantly by placing a few friction dampers between the mirrors.
We have also varied the damper's mass and observed that increasing the mass helps to reduce the mechanical noise, but the enhancement eventually saturates.
In our cavity system equipped with flexural translation stage, this small modification allows us to reduce the noise by roughly an order of magnitude from $\sim$1~nm to $\sim$0.1~nm with only three dampers. 
This noise reduction comes mainly from the restriction of motional modes along the dampers due to friction in the stick regime. 
The damping effect can be pretty significant even for small and light dampers, hence can be easily applied to any system requiring additional mechanical stabilization.
There is also an added advantage that the dampers can be used in HV settings.
