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.

通过材料研究计划的奖项，加利福尼亚大学圣塔芭芭拉分校将开发一个激光驱动的Terahertz系统，该系统将为高分辨率的线性Terahertz材料，材料结构和设备提供新的研究工具。该仪器将传递可调辐射的微量流量，最高为〜1 terahertz（THZ）。 高于〜1 terahertz的功率将大大降低，但足以适应材料和材料结构的线性高分辨率光谱。 该系统最多可使用可激发和采样方法的适当方法，以超过现有网络分析仪能力的频率来测试最新电子产品的性能。 同时，该系统将提供一个测试床，以探索新的非线性材料和设备，以通过光电导率和非线性敏感性通过光电辐射的光学差异频率产生。该新工具的研究和开发将为博士后研究人员提供跨学科的教育和培训，并向物理，材料科学和固体电子电子学领域的毕业生和本科生提供。%%;从加利福尼亚大学圣塔芭芭拉大学（University of Califortration of Santa Barbara设备。电磁光谱的Terahertz一部分，从100 GHz到10 THz，科学丰富，但相对较差。 激光驱动的Terahertz系统将为材料，材料结构和设备的高分辨率线性Terahertz光谱提供新的研究仪器。 该新工具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，材料科学和固态电子学中使用该工具的研究生和本科研究人员提供跨学科的教育和培训。 该仪器将传递可调辐射的微量流量，最高为〜1 terahertz（THZ）。 高于〜1 terahertz的功率将大大降低，但足以适应材料和材料结构的线性高分辨率光谱。
