recheck of laser parameter

Since we find the beam parameter changed because we change the laser power, we did the beam parameter measurement again. Now the power of laser is 277mW.

This is for AUX 1, the laser that will be used for the coherent control. A first characterization was done and reported in entry 666. It seems compatible with the new measurement.
