摘要
针对全固态皮秒THz波参量振荡器,设计了一种蝴蝶型腔结构.并采取优化设计MgO:LiNbO3(MgO:LN)晶体掺杂浓度、耦合输出方式和最佳晶体长度及提高THz波的转化效率等措施,实现全固态皮秒THz波参量振荡器的高性能运转.计算结果为全固态皮秒THz波参量振荡器基于MgO:LN晶体差频产生可调谐THz波辐射的实验研究提供进一步深入的理论基础.
An external cavity is developed for terahertz-wave parametric oscillators pumped by all solid state picosecond lasers (ps-TPOs). To achieving the ps-TPOs high-powered operation, the doped concentration of the MgO: LN crystal, the focusing spot size in MgO: LN crystal, the length of the MgO: LN crystal and the optical-to-THz conversion efficiency are optimally designed and calculated. The calculated results can provide a comprehensive theoretical basis for the ps-TPOs using difference- frequency method to produce tunable terahertz-wave radiations in MgO: LN crystal.
