During the ghost beam shift, we wanted to increase SC power on the bench to increase the visibility of ghost beams. However, by rotating the waveplate of the power control right after the output collimator of the fiber, we could not raise the power above about 3 mW, which seems to indicate an abnormally high power loss from the laser head to the collimator output (it was expected to be able to reach a few tens of mW). The laser injection current (that we did not change) was set to about 1.3 A, which should be nominal and close to maximum output power (500 mW), although this needs to be confirmed.
