We systematically study the optimization of highly efficient terahertz (THz) generation in lithium niobate (LN) crystal pumped by 800 nm laser pulses with 30 fs pulse duration. At room temperature, we obtain a record optical-to-THz energy conversion efficiency of 0.43% by chirping the pump laser pulses. Our method provides a new technique for producing millijoule THz radiation in LN via optical rectification driven by joule-level Ti:sapphire laser systems, which deliver sub-50-fs pulse durations.

研究了稀疏孔径镜面硬点与边缘传感器布局对稀疏孔径相对位姿控制精度的影响。利用离散孔径镜面几何特性, 建立了一个由7个圆形子孔径组成的主镜模型, 并推导了子孔径间相对位姿控制矩阵。鉴于控制矩阵条件数大这一特点, 采用广义最小二乘法求解, 引入岭估计并给出了控制矩阵误差函数上确界, 分析了128种边缘传感器与硬点布局以及几何距离对控制矩阵条件数的影响。仿真结果表明: 硬点和边缘传感器的几何布局与系数矩阵存在内在联系; 离散孔径相对位姿控制系数矩阵存在严重的复共线现象,法矩阵出现严重病态; 硬点布局与改善系数矩
夏克-哈特曼波前传感器(SHWS)通常要求每个子透镜的对应光斑必须在其相应的子孔径范围内,以方便确认光斑与子孔径间的对应关系。提出了一种基于软件的识别方法即迭代外推法,可以在光斑跑出其对应子孔径范围时,仍能确认每一个光斑对应的子孔径,使SHWS具有更大的动态范围。该方法首先找到一个可排序的3×3光斑阵列,并建立关于光斑质心坐标与其行列序号间关系的多项式函数,以预估和搜索相邻光斑;然后利用已搜索光斑
