 Title: Fundamental Mode TEM00 

The current setup for the SBox has a beam viewer and 2 photodiodes placed at reflection and transmission.

The CW laser piezoelectric crystal was driven using the lase lock system to observe the 00 mode.

Mode Observed and has no reflection (from what was previously seen)

higher order modes are resonating with 00 mode , example 11 mode (shown in image attached)

the coupling is yet to be seen and measured.
