Broadband near-to-shot-noise suppression of the intensity noise from a continuous-wave (cw) fiber laser at 1550 nm is demonstrated at GHz-frequencies using feed-forward phase-matched destructive noise interference impressed onto the optical signal with a fiber electro-optic power modulator. The scheme is independent of the laser frequency and therefore is(More)
This paper reports on the detailed implementation and on-sky performance evaluation of an adaptive vibration cancellation (AVC) algorithm integrated into a medium order Adaptive Optics system (MACAO) currently operated at the European Southern Observatory in Paranal Chile. With respect to the previous contributions from the authors on the subject, this(More)
