The SBox Length (FSR), was changed to match the repetition rate of the Menhir pulsed laser Frep = 216.6625 MHz
It was changed by removing the 2 D-shaped mirrors placed between M1 and M2, distance between M1-M2 ~= 169 mm
it was still needed to be adjusted with M1 motor to reach the correct FSR.
The pulsed laser is placed on the able with injection into a fiber
The Finesse of the cavity has progressed from ~2500 to ~ 18 000
** Note: PowerPoint attached shows the progress over the last two weeks on the laser and |
