1310nm probe imaging unit translation stage aligned parallel to the laser

Members: Manuel, Kuroki

We aligned the imaging unit of the 1310nm probe laser. The IU translation stage is translating parallel to the beam (at 0.1rad with the pump)

The DC signal we got at the detector is about 4V. With a probe laser current of 200mA.

Next step is to adjust the distances of the parts in the IU to make the sharp image on the detector of a blade at the crossing point.
