With support from the Chemistry Research Instrumentation and Facilities Instrument Development program, Geoffrey Blake of the Department of Chemistry and Scott Fraser of the Department of Biology at California Institute of Technology in conjunction with Peter H. Siegel of the Jet Propulsion laboratory will develop a compact integrated time domain and frequency domain Terahertz spectrometer. The novelty of this instrument development project is the generation of the two phase coherent THz pulses from two 20 fs Ti:Sapphire lasers, which has not been demonstrated. This system will operate as a user facility allowing for broad access of use. The system will be used in several applications including (1) biological imaging to characterize nano-materials and biological systems, (2) national security imaging applications and (3) optoelectronic applications which may lead to breakthroughs in telecommunications and optical computing. A wide range of additional students, postdoctoral fellows and senior researcherswill benefit from the anticipated THz capabilities. Outreach activities through existent programs will encourage the participation of undergraduates and K-12 students.

在化学研究仪器和设施仪器开发项目的支持下，加州理工学院化学系的Geoffrey Blake和生物系的Scott Fraser与喷气推进实验室的Peter H. Siegel将共同开发一种紧凑的时域和频域集成太赫兹光谱仪。该仪器开发项目的新颖之处在于从两个20 fs Ti:Sapphire激光器产生两相相干太赫兹脉冲，这尚未被证明。该系统将作为用户设施运行，允许广泛使用。该系统将用于几个应用，包括(1)生物成像，表征纳米材料和生物系统；(2)国家安全成像应用；(3)光电应用，可能导致电信和光学计算的突破。更多的学生、博士后和高级研究人员将从预期的太赫兹能力中受益。通过现有项目开展的外展活动将鼓励本科生和K-12学生的参与。
