Comment to Preparing for scanning the Tama-size sapphire sample (Click here to view original report: 284)
In the following table, there is a summary of last measurements
| raw data | filtered data | |||
| depth |
absorption ppm/cm |
precision ppm/cm |
absorption ppm/cm |
precision ppm/cm |
| 0mm | 13.0 | 7.2 | 12.9 | 1.7 |
| 5mm | 12.4 | 7.3 | 12.3 | 1.6 |
| 10mm | 6.8 | 7.4 | 6.8 | 1.2 |
| 15mm | 9.8 | 8.6 | 9.7 | 1.3 |
| 20mm | 9.3 | 7.9 | 9.3 | 1.1 |
| 25mm | 9.0 | 8.3 | 8.9 | 1.3 |
| 30mm | 7.5 | 6.4 | 7.5 | 0.9 |
"Depth" is the position of the incident sample surface with respect to the pump-probe cross point. According to the refraction effect, the cross point position inside the sample is double, so, given the sample thickness 60mm, the depth 30mm refers to the measurement at the opposite surface of the sample.
I attach the plots of the 6 sets of measurements.
