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计划的支持下，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型集成仪器时域和频域太赫兹光谱仪。该仪器开发项目的新颖之处在于从两个 20 fs 钛宝石激光器生成两相相干太赫兹脉冲，这一点尚未得到证实。该系统将作为用户设施运行，允许广泛的使用。该系统将用于多种应用，包括（1）生物成像来表征纳米材料和生物系统，（2）国家安全成像应用和（3）可能导致电信和光学计算突破的光电应用。 更多的学生、博士后研究员和高级研究人员将受益于预期的太赫兹能力。通过现有计划开展的外展活动将鼓励本科生和 K-12 学生的参与。
