Preparation of AZTEC #5 absorption measurement
I removed #3 without rotating it : Please don't touch the holder nor the mirror as we need to precisely mark the c-axis orientation
I realigned and characterized with razor blades both the probe and pump beam as reported in figures 1 and 2.
Note that the x axis of these figures is somewhat random (just corresponds to translation stage z position with the razor blades installed)
I got good values of AOI, beam sizes and crossing point.
I measured the surface reference sample :
Pin = 29.6e-3
ac = 0.4355
dc = 4.28
acdc = 0.10175
R = 15.625 /W
(3% change wrt # absorption)
filename = 'Mon, Jul 11, 2022 8-40-39 PM'
xyz = 327.093,119.965,35
ziu = 68
Pin = 29.6e-3
ac = 0.4355
dc = 4.28
acdc = 0.10175
R = 15.625 /W
(3% change wrt #1 absorption)
filename = 'Mon, Jul 11, 2022 8-40-39 PM'
xyz = 327.093,119.965,35
ziu = 68
Then I measured the bulk reference sample :
AC_bulkref =0.0839
DC_bulkref = 5.05
P_in = 29.8e-3
ACDC = 0.0166
P_t = 16.3e-3
z1 = 32.2
z2 = 35.4
z_center = 33.2
R_bulk = 0.7242 cm/W
filename = 'Mon, Jul 11, 2022 9-05-35 PM'
Also got good values wrt previous measurements
I installed the 1.5 inch sapphire sample, realigned the DC with ziu = 65.49 mm.
I did a long z scan with Pt = 5.51W (Mon, Jul 11, 2022 9-47-22 PM)
Finally, I started a XY measurement with 10 mm radius at z_center = 28.7 mm, x = 327.093 mm and y = 119.965 mm.
AC_bulkref =0.0839
DC_bulkref = 5.05
