    "abstract": "We demonstrate phase lock of two \u003e1.6W Titanium:sapphire lasers with a phase\nnoise of -138dBc/Hz at 1MHz from the carrier, using an intra-cavity\nelectro-optic phase modulator. The residual phase variance is 2.5 10^(-8)rad^2\nintegrated from 1Hz to 10kHz. Instantaneous offset frequency steps of up to\n4MHz are achieved within 200ns. Simultaneous atom interferometers can make full\nuse of this ultra-low phase noise in differential measurements by suppressing\ncommon influences from vibration of optics.",
