研究了完全空间简并光学参量振荡器(自成像OPO)出射光的空间量子特性。我们发现，这种装置对大于相干的区域产生局域压缩，其大小取决于晶体长度和泵浦宽度。此外，它还在远场产生局部EPR光束。通过对系统本征模的计算表明，对于实际的实验参数，它是高度多模的。
We investigate the spatial quantum properties of the light emitted by a perfectly spatially degenerate optical parametric oscillator (self-imaging OPO). We show that this device produces local squeezing for areas bigger than a coherence are that depends on the crystal length and pump width. Furthermore, it generates local EPR beams in the far field. We show, calculating the eigenmodes of the system, that it is highly multimode for realistic experimental parameters.
