With this award from Instrumentation for Materials Research Program the University of California, Santa Barbara, will develop a Laser Driven Terahertz System which will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The instrument will deliver microwatts of tunable radiation up to ~1 terahertz (THz). Above ~1 terahertz the power will be substantially less but more than adequate for linear, high-resolution spectroscopy of materials and material structures. Up to 1 terahertz, with suitable methods of excitation and sampling, the system will also be used to test the performance of state-of-the-art electronics at frequencies that exceed the capability of existing network analyzers. At the same time, the system will provide a test bed to explore new non-linear materials and devices for optical difference frequency generation of terahertz radiation by photoconductivity and non-linear susceptibility. The research and development of this new instrument will provide interdisciplinary education and training for postdoctoral researcher and to graduate and undergraduate students in physics, materials science and solid state electronics.%%%With this award from Instrumentation for Materials Research program the University of California Santa Barbara will develop a Laser Driven Terahertz System which will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The terahertz part of electromagnetic spectrum, from 100 GHz to 10 THz, is science rich but relatively technology poor. The Laser Driven Terahertz System will provide new research instrumentation for high-resolution linear terahertz spectroscopy of materials, material structures, and devices. The research and development of this new instrument will provide interdisciplinary education and training for the post-doctoral researcher committed to the project and to graduate student and undergraduate researchers who will use the instrument in physics, materials science and solid state electronics. The instrument will deliver microwatts of tunable radiation up to ~1 terahertz (THz). Above ~1 terahertz the power will be substantially less but more than adequate for linear, high-resolution spectroscopy of materials and material structures.

凭借材料研究计划仪器的这一奖项，圣巴巴拉的加州大学将开发一种激光驱动太赫兹系统，该系统将为材料，材料结构和设备的高分辨率线性太赫兹光谱提供新的研究仪器。该仪器将提供微瓦的可调谐辐射高达~1太赫兹（THz）。 在~1太赫兹以上，功率将显著地更小，但对于材料和材料结构的线性、高分辨率光谱来说绰绰有余。 通过适当的激励和采样方法，该系统还将用于在超过现有网络分析仪能力的频率下测试最先进的电子设备的性能。 同时，该系统还将提供一个试验平台，用于探索通过光电导和非线性磁化率产生太赫兹辐射的光学差频的新型非线性材料和器件。这种新仪器的研发将为博士后研究人员以及物理学、材料科学和固态电子学的研究生和本科生提供跨学科的教育和培训。凭借材料研究计划仪器的这一奖项，加州大学圣巴巴拉将开发一种激光驱动太赫兹系统，该系统将为材料，材料结构和设备的高分辨率线性太赫兹光谱提供新的研究仪器。电磁频谱的太赫兹部分，从100 GHz到10 THz，科学丰富，但技术相对贫乏。 激光驱动太赫兹系统将为材料、材料结构和器件的高分辨率线性太赫兹光谱学提供新的研究仪器。 这种新仪器的研究和开发将为致力于该项目的博士后研究人员以及将在物理学，材料科学和固态电子学中使用该仪器的研究生和本科生研究人员提供跨学科的教育和培训。 该仪器将提供微瓦的可调谐辐射高达~1太赫兹（THz）。 在~1太赫兹以上，功率将显著地更小，但对于材料和材料结构的线性、高分辨率光谱来说绰绰有余。
