It was simply the new scheme to inject 2 RF frequencies in a single EOM.      125   Thu Feb 3 18:59:10 2022 Manar Amer Fixed report lasers and optics | detectors and electronics ThomX igloo Cavity Lock and Finess measurment to measure the Finesse, instead of having 2x EOM for the PDH and for the      126   Thu Feb 3 19:01:04 2022 Manar Amer Fixed report lasers and optics | detectors and electronics ThomX igloo Cavity Lock and Finess measurment After changing the way of injecting modulation for PDH and modulation for FSR      127   Fri Feb 4 10:59:56 2022 Manar Amer Fixed report lasers and optics | detectors and electronics ThomX igloo Cavity Lock and Finess measurment one thing which could reduce the Finesse is the L-shape metal piece if it is slightly inserted in the FP-cavity mode path.      129   Fri Mar 11 12:59:35 2022 Manar Amer Fixed report lasers and optics ThomX igloo Cavity beam Image Updated beam image after change on the mode axis. Taken after P4.      132   Mon Mar 14 18:39:40 2022 Manar Amer Fixed info mechanics | lasers and optics | detectors and electronics ThomX igloo Current Installed Setup Attached is the current setup in ThomX      135   Tue Mar 22 21:19:48 2022 Manar Amer Fixed report lasers and optics ThomX igloo Alphanov amplifier Beam Profile Today: Manar, Ronic and Aurlien started the study of the beam profile of the alphanov amplifier at high power.  8x
