论文摘要
我们研究了复杂非线性光学过程的准确完整宽带模拟。开发了时间域中的数学模型和数值模拟技术，以模拟复杂的非线性光学过程，而没有通常使用的使用慢慢变化的包膜近似。我们通过数值模拟说明了准确性。此外，它们被用来阐明定期粘二氯酸酯（PPLN）（包括光谐式产生）中的Thz产生。
We investigate the accurate full broadband simulation of complex nonlinear optical processes. A mathematical model and numerical simulation techniques in the time domain are developed to simulate complex nonlinear optical processes without the usual used slowly varying envelope approximation. We illustrate the accuracy by numerical simulations. Furthermore, they are used to elucidate THz generation in periodically poled Lithium Niobate (PPLN) including optical harmonic generation.
