We show how to reach high fidelity NOON states with a high count rate insideoptical interferometers. Recently it has been shown that by mixing squeezed andcoherent light at a beamsplitter it is possible to generate NOON states ofarbitrary N with a fidelity as high as 94%. (Afek I. et al. Science 328, 879(2010)). The scheme is based on higher order interference between "quantum"down-converted light and "classical" coherent light. However, this requiresoptimizing the amplitude ratio of classical to quantum light thereby limitingthe overall count rate for the interferometric super-resolution signal. Wepropose using coherent-beam-stimulated non-collinear down converted light asinput to the interferometer. Our scheme is based on stimulation ofnon-collinear parametric down conversion by two-mode coherent light. We havesomehow a better flexibility of choosing the amplitude ratio in generating NOONstates. This enables super-resolution intensity exceeding the previous schemeby many orders of magnitude. Therefore we hope to improve the magnitude ofN-fold super-resolution in quantum interferometry for arbitrary N by usingbright light sources. We give some results for N=4 and 5.
