摘要

在应用强场太赫兹波时，提高单晶体的太赫兹辐射效率至关重要。我们设计了一种梯形铌酸锂棱镜，在太赫兹波侧入射时，可将飞秒激光反向反射到晶体的对称面上。与传统腔体相比，圆形腔体的泵浦功率到太赫兹脉冲功率的转换效率提高了 36%。研究结果表明，利用采样复用泵浦可以显著提高太赫兹产生的效率。

Enhanced Terahertz Emitter by Multiplexing Pump Titled Pulse Front in LiNbO3 Crystal

It is crucial to enhance the efficiency of terahertz radiation in a single crystal for the application of intense field terahertz waves. We devise a trapezoidal lithium niobate prism that, upon side incidence of the terahertz wave, retroreflects the femtosecond laser onto the crystal’s symmetric plane. The conversion efficiency of pump power to THz pulse power for circular cavity increases by 36% compared to that of the conventional cavity. The findings demonstrate that the utilization of sample multiplexing pump can significantly enhance the efficiency of terahertz generation.
