【摘要】 本文报道了利用BaTiO₃晶体的两波耦合和自泵浦效应,实现高位相共轭反射率的方法。给出位相共轭反射率R随两耦合光束之间的夹角2θ,以及光束强度比β变化的实验结果。在适当的条件下（2θ≈35°,β=2600）,得到共轭反射率大于35。更多还原

【Abstract】 This paper reports a method for obtaining high phase-conjugate reflectivity, which combines two-wave coupling and self-pumping effect in a BaTiO3 crystal. The dependence of the phase-conjugate reflectivity upon the beam intensity ratio and the angle between two coupled beams are given. Experimental results show that under proper conditions the phase-conjugate reflectivity is greater than 35.更多还原
