AlGasAs coating measurement

[Shalika, Marc]

Measuring Jones Matrrix of AlGaAs coating

The sample is same as mentioned by Manuel in 746. We used the mounting technique as mentioned by Manuel in 746. But, we put in a mount where we can tune the alignment as well, i.e in  a 2inch mirror mount. We first practiced putting a sample with no polish to see if the mount is fine. After being fully assured that the mount was indeed fine(like the screw will not touch the wafer or the wafer will not fall off, etc.), we then put the 0.5mm thick sampple. (pic1, pic2)

We setup a small clean room (taken from PCI). The AlGaAs was kept inside it. (pic3, pic4)
