9724436 Sherwin A tunable, far-infrared, picosecond source will be developed based on the free electron laser (FEL) facility at the University of California-Santa Barbara (UCSB). The pulsed, far- infrared source will support research in several areas of condensed matter physics, mostly nonlinear dynamics of semiconductor heterostructures and of superconductors at terahertz frequencies. %%% The light source to be developed will fulfill a current need for a short-pulse, far-infrared user facility in the country. The new FEL capability has potential applications in other areas besides condensed matter physics, such as molecular spectroscopy, molecular chemistry, and biophysics. ***

9724436舍温基于加州大学圣巴巴拉分校(UCSB)的自由电子激光(FEL)设备，将开发一种可调谐的远红外皮秒光源。脉冲远红外源将支持凝聚态物理的几个领域的研究，主要是半导体异质结构和太赫兹频率超导体的非线性动力学。将开发的光源将满足该国目前对短脉冲、远红外用户设施的需求。新的自由电子激光能力在凝聚态物理之外的其他领域也有潜在的应用，如分子光谱、分子化学和生物物理。***
