Beam-pointing fluctuations in gain-guided amplifiers
S. J. Kuo, D. T. Smithey, M. G. Raymer · Physical Review Letters · 1991
We report a measurement of the quantum-mechanical beam-pointing fluctuations in the output of a gain-guided, single-pass amplifier using stimulated Raman scattering. The experimental result is in reasonable agreement with a theoretical model that incorporates the effects of excess spontaneous noise associated with the transverse modes of a gain-guided amplifier.
