Measurement of the pulse was done at the end of the afternoon, Pulse Duration FWHM = 12.9 ps
After a long process of adjusting the alignment and angle of the crystal inside the device
The power input on the PulseCheck device should be above the sensitivity, in our case we had 1 mW input.
To reach it, we removed one of the wedge mirrors and used dielectric mirrors with an amplification of 20% ~ 25 W direct output power.
The input to the pulsecheck must be horizontally polarized, which is why we used a polarizing beam splitter (PBS).
For a better pulse shape, Victor adjusted the "beam distance" and "beam focus" nobs on the device.

The pulse duration from the amplifier compressor output will be measured using PulseCheck autocorelator
a first alignment of the device was done, continuation in the afternoon.
