Abstract

In this paper we review the field of terahertz (THz) sources which make use of the nonlinear, stimulated polariton scattering (SPS) process. A historical perspective of the technology is offered, in addition to an investigation of modern SPS-based THz sources. Breakthroughs in these source technologies have coincided with rapid developments in laser technology over the past 10 years. We are now in an age where pulsed SPS-THz sources are generating peak powers in excess of 50 kW, and continuous wave SPS-THz sources can be produced using diode pump powers as low as 2.3 W. The versatility of this approach to THz generation has enabled the generation of coherent THz radiation across continuous wave (CW), nanosecond-, and picosecond-pulsed modalities, with sources spanning the frequency range 0.5–13 THz. Being based on robust and well-developed, crystalline solid-state laser technology, these sources hold great promise as an enabling technology for a plethora of THz applications.

基于受激极子散射的太赫兹源

本文综述了利用非线性受激极化子散射(SPS)过程的太赫兹(THz)源的研究进展。除了对现代基于sps的太赫兹源的调查外，还提供了该技术的历史观点。这些光源技术的突破与过去10年来激光技术的快速发展相吻合。我们现在处于脉冲SPS-THz源产生峰值功率超过50 kW的时代，连续波SPS-THz源可以使用低至2.3 W的二极管泵浦功率产生。这种太赫兹产生方法的通用性使连续波(CW)、纳秒和皮秒脉冲模式的相干太赫兹辐射能够产生，源的频率范围为0.5-13太赫兹。基于强大和发达的晶体固态激光技术，这些光源作为一种使能技术，在太赫兹的大量应用中具有很大的前景。
