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.

基于受激极化子散射的太赫兹源
摘要 在本文中,我们回顾了利用非线性受激极化子散射 (SPS) 过程的太赫兹 (THz) 源领域。除了对基于 SPS 的现代太赫兹源的调查之外,还提供了该技术的历史视角。这些光源技术的突破与过去 10 年激光技术的快速发展相吻合。我们现在处于脉冲 SPS-THz 源产生超过 50 kW 峰值功率的时代,而连续波 SPS-THz 源可以使用低至 2.3 W 的二极管泵浦功率产生。这种太赫兹生成方法的多功能性使得在连续波 (CW)、纳秒和皮秒脉冲模式中生成相干太赫兹辐射成为可能,源的频率范围为 0.5-13 THz。
