1) Note: The OneFive laser used for experimenting is the one for the SBox
but, for now only this laser arrived from the company so we are doing tests (measuring the spectrometer and power ) on it inside the ThomX cavity clean room.
2) on the RF - Analyzer the value of the laser repetition frequency is measured:
* 17/12/2020 (when first turning it on, the day before in the afternoon ) ---> 133.330 700 MHz
* this day18/12/2020 (in the afternoon, after a full day to it being on) ----> 133.330 840 MHz
they have a difference of 140 Hz this comes from normal thermal expansion inside the laser which is ok, as it changed over the course of a day of operating the laser.
3) the power meter is connected to the desktop in the ThomX cavity room and a TeamViewer application has been installed to observe the measurement over the period of several days mentioned (15?) remotely.
to access this you need to have an account on the application and allow your account to access it from the desktop.
for now, only Ronic and Manar has remote access.

After turning on, one can see the 133.33MHz Onefive output power for ~40min with OD2 filter (~/20). So the real output power is ~57mW. A measurment over several days (15?) should come in few weeks.
The spectrum here has been taken one day after turning on the Onefive (see Fig. 133_spectrum_full and 133_spectrum). One can see the central wavelength of 1030.5 nm and a small peak at 1054nm (see Fig. 133_spectrum2).
