 Rebuild our setup (removed the cube) to test the fiber. The fiber will enable us to get a nice Gaussian beam profile with which we can work in the future. Built in the fiber in a very adventurous setup because we do not yet have a mount printed. Tried to couple in the laser but did not succeed yet. The fiber is built very close to the first mirror and quite far to the second to decouple place and angle of the beam entering the fiber. As detector tried the bare eye (without collimating optics at the fiber end). Need complete darkness to get first signal to optimize on next time. Rebuild our setup (removed the cube) to test the fiber.

 Way forward: We need a proper mount for the fiber collimator, such that we can use a pinhole to pre-align the beam as good as possible for getting a first signal. With unclear exact mounting angle, it will get very difficult to get a first signal. Back tracking the backreflection did not yet lead to success. Way forward: We need a proper mount for the fiber collimator, such that we can use a pinhole to pre-align the beam as good as possible for getting a first signal.
