This Morning with Victor the amplifier was turned on @ 20% amplification (output ~ 9 W ) for approximately 3 hours and no error appeared.
I took data of the beam profile at different points without a lens after the 2 wedges
@ 0% (only pump beam), output ~ 300 mW (taken from previous data) , output after 2 wedges 2.2 uW
@ 20% amplification , output ~ 9 W (taken from previous data) , output after 2 wedges 58.6 uW
fit to be added after processing the Beam Profiles data files.
Data with the lens to be taken !!

Adding the schematic of the measurements.,
the 4° Beam Deviation, AR Coating ( B coating)
The 3 data points taken of the beam profile are fitted in Gaussian Beam with taking the beam waist at the output of the compressor box.
Background is subtracted for all data points, the fit is more than 90% for all points.
a reading was observed with distance less than 200 cm before the periscope and the fit starts to degrade
reason probably be related to the bump beam !!! To be investigated by placing an iris.
