-====== Ring-down Box ====== 
-===== Application of the ring-down box ===== 
-You can measure the finesse of a resonator with the ring-down box.

-==== Measurement Method ==== 
-==== Evaluation ==== 
-Use this formula to analyse the datapoints:\\ y(x)=A*exp^(-x/t)+y0 with x:=time, t:= delay time\\ 
- 
-Afterwards calculate the finesse with F=2pi*t*FSR with FSR:=free spectral range.
