Mirror configuration

Parameter

Radius of curvature of mirror R1: R1= 1 m

Radius of curvature of mirror R2: R2= 1 m (Incoupling side)

Wavelength: λ= 1542.0 nm

Length between the resonator mirrors: L= 480 mm

Beam radius at cavity-waist: w0

Beam radius at mirror: w1, w2

Distance between:

mirror R1 and mirror R2: L

mirror R2/lense 1 and lense 2: X

mirror R2/lense 1 and collimatorlense: 600mm - X

615mm = optical way of the incoupling breadboard (450mm) + thickness breadboard (10mm) + distance between breadboard and vacuumchamber (30mm) + distance between vacuumchamber and cavity mirror R2 (130mm)

collimatorlense and fiber: 2.75 µm

We used the programm Strahl.exe(IQ) or STRAHLFP.EXE (same software, but different names). Step 1: Beam waist calculation from resonator
