Coupling into a 50-50% fiber coupler using the Thorlabs XYZ table NanoMax TS.
We reached 117mW after the 50% arm which means we coupled about 230mW (the coupling better than 50%).

Installation of the MIKAN.
powermeter (with OD1) just after the oscillator shows 440mW for 4A of the MIKAN pump current.

Installation of a periscope as the oscillator beam position is very close to the table... not easy to put devices at this height (be aware to use proper wavelength range mirrors: Thorlabs BB1-E03)
Installation of a HALF waveplate to align beam polarisation on the isolator axis
Installation of a High power isolator (the one of ThomX): Newport ISO-FRDY-05-1030-N
powermeter (with OD1) just after the isolator shows 427mW
