相位匹配容量是评价一种新型非线性光学晶体应用前景的重要因素。利用一个小的单晶，通过Kurtz-Perry方法获得准确可靠的PM曲线确实是至关重要的。本文报道了一种新型硼酸盐NLO晶体Rb7SrY2(B5O10)3(I)，并研究了微[B5O10]基团排列对其双折射性能的影响。有趣的是，合成的多晶粉末和研磨后的单晶分别表现出不同的PM和非PM行为。结合理论计算和分析，证明了其在1064 nm激光二次谐波产生过程中是非相位匹配的。
Phase-matchable (PM) capacity is an indispensable factor in evaluating the applicable prospect of a new nonlinear optical crystal. Obtaining an accurate and credible PM curve by the Kurtz–Perry method using a small single crystal is indeed crucial. Here, we reported a new borate NLO crystal Rb7SrY2(B5O10)3(I) and studied the influence of the arrangement of micro-[B5O10] groups on its birefringence. Interestingly, the synthesized polycrystalline powder and grinded single crystal display divergent PM and non-PM behavior, respectively. Combining theoretical calculations and analysis,Iis demonstrated to be non-phase matchable for the second-harmonic generation (SHG) process of a 1064 nm laser.
