用Maker条纹方法测量了硼磷酸盐晶体BaBPO5的非线性光学系数d11(BaBPO5) =(0.439±0.002)d36(KH2PO4),d12(BaBPO5) =(0.425±0.008)d36(KH2PO4),相应的相干长度为:l11=16.985±0.301μm,l12=16.972±0.304μm。确定了非线性光学系数的相对符号,d11(BaBPO5)和d12(BaBPO5)符号相反。BaBPO5晶体激光损伤阈值大于900 MW/cm2。
The nonlinear optical coefficients of BaBPO5 = (0.439 ± 0.002) d36 (KH2PO4), d12 (BaBPO5) = (0.425 ± 0.008) d36 (KH2PO4) and the corresponding coherence length As follows: l11 = 16.985 ± 0.301μm, l12 = 16.972 ± 0.304μm. The relative sign of the nonlinear optical coefficient is determined, with the sign d11 (BaBPO5) and d12 (BaBPO5) opposite. BaBPO5 crystal laser damage threshold greater than 900 MW / cm2.
