Parameter

Calculation

We used the programm Strahl.exe (@IQ)

Step 0: Choose Parameter

Step 1: Beam waist calculation from resonator

→ Waistradius: w2= 283,1 µm, w1= 301,8 µm
→ FSR = 2,498 GHz

Step 2:

The values of the Waistradius and Strahlradius must not change!!!

Step 3:

Step 4: Playing with the parameters X, Y and Z for the best Überlapp

Lense focal length of Lense 2 Z [mm] 500 300
Typ LA1908-C AC254-300-C
Distance between mirror R2 and lense 2 X [mm] 504 300
Überlapp [%] 79 54
