摘要
回顾了基于倾斜波前技术并利用飞秒激光抽运铌酸锂晶体产生高能强场太赫兹辐射脉冲源的研究背景和发展历程,系统地介绍了倾斜波前装置中各组成部分对太赫兹辐射脉冲的能量转化效率以及发射特性的影响,提出了利用这种技术产生mJ量级的超强太赫兹源的可能途径,展示了强太赫兹源的潜在应用价值。
We review the research background and development history of the generation of high-energy strong-field terahertz radiation through the tilted-pulse-front technique in lithium niobite crystals driven by femtosecond laser pulses.We systematically analyze the influence of each component in the tilted-pulse-front setup on the energy conversion efficiency and emission properties of terahertz radiation and discuss the feasibility of the generation of mJ terahertz pulses through the proposed method.Further,the numerous promising applications of strong-field terahertz sources are demonstrated.
