We show how stimulated parametric processes can be employed in experiments on beyond the diffraction limit to overcome the problem of low visibility obtained by using spontaneous down conversion operating in the high gain regime. We further show enhancement of the count rate by several orders when stimulated parametric processes are used. Both the two photon counts and the visibility can be controlled by the phase of the stimulating coherent beam.
我们展示了受激参量过程如何应用于超越衍射极限的实验中，以克服在高增益 regime 下使用自发下转换所获得的低可见度问题。我们还进一步表明，当使用受激参量过程时，计数率可提高几个数量级。双光子计数和可见度都可以通过激发相干光束的相位来控制。
