磷酸钛氧铷。主要应用在非线性和电光领域。将KTP中K原子全部被Rb原子取代后即变成RTP.RTP是一种优良的电光晶体，尤其适合于制作Q开关。与同类晶体相比, RTP晶体的抗光损伤阈值较高, 更适合于高功率<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>的二倍频（SHG）和光参量振荡（OPO）等非线性应用。 此外, 由于具有较高的电阻率, RTP晶体可用于许多电光器件中, 还适合作为周期极化基底<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>, 用来制作周期极化RTP晶体器件。RTP电光Q开关是采用两块RTP晶体配对温度补偿设计，光束沿Y 或 X 轴传播，Z面镀电极，光束偏振沿通光面对角线方向。两块RTP电光晶体补偿自然双折射的示意图。两块晶体均垂直主轴切割，光束沿y方向传播，通光长度为L，，在晶体的:方向加电场，电极间距为d。放在晶体前端的偏振片的偏振方向与二轴成45角。当两块RTP晶体体正交放置时，自然双折射部分相互抵消，自然双折射得到了很好的补偿。而且用两块RTP晶体电学上并联时产生兀相位延迟所需的半波电压仅为单块RTP电光Q开关的一半<br /> <br /> 图4.1-2 双RTP晶体补偿自然双折射<br /> RTP是高重频电光Q开关的优选晶体，其应用范围可从350-4500nm。RTP晶体相变点和电导率较低，单筹化处理较容易，具有抗光损伤阈值高，插入损耗低，无压电振铃效应，不潮解等特性。RTP晶体与BBO晶体电光开关的性能对比:: 在高重复频率（30 kHz）时, RTP晶体和BBO晶体电光调Q开关的不同特性。BBO一块晶体开关由2.5x2.5x25mm3晶体构成, RTP晶体开关由两块6x6x7mm3晶体构成。在30 kHz 下, BBO晶体开关已经出现明显的压电振荡现象, 而RTP晶体开关无振荡现象。</td></tr></table> </div> <div id="comment_532906" class="cm"> </div> <div
