所提出的研究是探索在输入短脉冲由于脉冲群速度的差异而产生的二次谐波脉冲在时间上偏离的情况下,如何有效地产生二次谐波。人们的注意力将集中在大规模罢工制度上。研究聚焦和泵浦耗竭对非线性转换效率的影响。所提出的研究将阐明与这种相对未被探索的大时间行走机制相关的新现象学,并扩展关于二次谐波产生及其在便携式高效蓝光和紫外线源中的应用的基本知识。
英文摘要
The proposed research is to explore efficient second harmonic generation under the conditions where the generated second harmonic pulses walk off in time from the input short pulse due to the difference in the group velocities of these pulses. Attention will be focused on the large walkoff regime. Effects of focusing and pump depletion will be investigated to optimize the nonlinear conversion efficiency. The proposed research will elucidate the novel phenomenology associated with this relatively unexplored large temporal walkoff regime and expand the fundamental knowledge about second harmonic generation and its applications for portable and efficient blue and ultraviolet sources.
