    keyword=Transverse laser #3: fiber changed and realignment

    During the long Controlled Access today, I replaced the burnt fiber of the transverse
    laser #3, checked is the laser was still working (that is the case) and checked the quater-waveplate angle. The angle was fine and the back reflexion looks normal in intensity.
    Then with Jian-Ping we checked the alignment and worked on the back reflexion:
    we found two back reflexion spots (the main one and another weak one) and we worked to bring them as far as possible from the fiber.
    We turned on the laser at full power and everything looks OK now.
