Ruderman 9360879 The efficient generation of the harmonics of important lasers such as Nd:YAG (1064 nm) and Ti:Sappahire (700-900 nm) depends upon the availability of single crystals which exhibit are nonlinear coefficients, high optical transparency, high laser damage threshold and good physical properties. KDP, KD*P, LiIO3 and CD* A crystals have been used for many years, and more recently BBO and LBO crystals have been found to offer significant advantages. Very recently, scientists at Shandong University in China reported on a technique or detwinning and removing domains in KIO3 crystals. They found that the nonlinear optical coefficient of single domain single crystal KIO3 was larger than that of KDP, BBO, and LBO. This makes KIO3 a very attractive new nonlinear crystal. We propose to grow KIO3 from solution by three techniques and to study the effects of temperature and pressure on the efficiency of detwininning and domain removal of as-grown crystals. The nonlinear optical coefficient, acceptance angel, and laser damage threshold of single domain KIO3 will be measured as well as the conversion efficiency for second and third harmonic generation of laser radiation form 700 to 1064 nm.

鲁德曼9360879 重要激光器如Nd：YAG（1064 nm）和Ti：Sappahire（700-900 nm）的谐波的有效产生取决于单晶的可用性，所述单晶表现出非线性系数、高光学透明度、高激光损伤阈值和良好的物理性质。 KDP、KD*P、LiIO 3和CD* A晶体已经使用多年，最近发现BBO和LBO晶体具有显著的优点。 最近，中国山东大学的科学家报道了一种技术，即在KIO 3晶体中消除孪晶和去除畴。 他们发现单畴单晶KIO 3的非线性光学系数大于KDP、BBO和LBO的非线性光学系数。 这使得KIO 3成为一种非常有吸引力的新型非线性晶体。 我们建议从三种技术的解决方案中生长KIO 3，并研究温度和压力的影响的解孪晶和畴去除的生长晶体的效率。 将测量单畴KIO 3的非线性光学系数、接受角和激光损伤阈值，以及700至1064 nm激光辐射的二次和三次谐波产生的转换效率。
