1310nm probe
we aligned the pump beam to maximize the AC signal of the surface reference sample, and we made a calibration scan with pump power 35mW.
Then we increased the power at the maximum and measured the crystalline coating with three different probe power: DC=1.01, DC=1.62, DC=2.54.
Then we plot the three scans together and the result is that the AC/DC overlaps.
We also repeated a scan with higher resolution in z.
