Acquisition of Equipment for an Enhanced Multiuser Ultrafast Laser Facility for Research and Education

这笔赠款支持为纽约州立大学布法罗分校用于研究和教育的增强型多用户超快激光设施购置设备。这些改进将通过购买三个系统部件来实现：1)固态泵浦系统，2)用于提高时间分辨光致发光的时间分辨率的扫描延迟单元，以及3)用于开发时间分辨差分传输和反射装置的延迟阶段。新设备将加强亚利桑那大学两个主要材料研究中心的现有和计划中的研究计划，以及化学、物理和电气工程系的其他研究计划。这将把时间分辨光谱学的研究扩展到近红外和中红外范围，提高光致发光的时间分辨率。它将使设备应用中对铁磁半导体的两个彩色泵浦/探头研究成为可能。它将为用于生物和化学探测器的深紫外光发射器以及用于电信应用的量子级联激光结构的研究做出新的贡献。我们希望它能够使用两种颜色光谱对生物材料进行新的研究。除了这个设施的科学价值，新的设备采购将对教育项目和整个社会产生更广泛的影响。这一改进后的设施将通过研究员的参与，提供一流的交钥匙超快激光设施的实践经验，从而有助于培训一批新的研究人员。它将允许在高水平实验研究方面接受较少培训的学生(包括本科生)熟悉正在进行的最先进的研究工作，从而激发对科学和工程的持续兴趣。我们预计，这将使当前的能源消耗(电力和冷却水)减少20倍。我们希望它能减少系统的空闲时间。我们预计它将提供最先进的多用户超快激光设备，将影响我们整个大学和我们其他机构的合作者的研究和教育努力。

This grant provides support for the acquisition of equipment for an enhanced multiuser ultra fast laser facility for research and education at SUNY Buffalo. These improvements will be accomplished by purchasing three system components: 1) a solid state pumping system, 2) a streak delay unit to improve temporal resolution for time resolved photoluminescence, and 3) a delay stage for the development of time-resolved differential transmission and reflection apparatus. The new equipment will enhance the existing and planned research programs in two major materials research centers at UB, as well as other research programs in the Departments of Chemistry, Physics and Electrical Engineering. It will expand the time-resolved spectroscopy studies to the near and mid-infrared range and improve the temporal resolution of photoluminescence. It will enable two color pump/probe studies of ferromagnetic semiconductors on ferromagnetic semiconductors for device applications. It will enable new contributions to the study deep UV emitters for biological and chemical detector applications as well as for quantum cascade laser structures for telecommunication applications. We expect itto enable novel studies of biological materials using two color spectroscopy. In addition to the scientific merits of this facility, the new equipment acquisition will have broader impact on education programs and the society at large. This improved facility will contribute to the training of a new class of researchers by offering hands-on experience with a top of the line turn-key ultra fast lasers facility through involvement of fellows. It will allow students with less training in high-level experimental research (including undergraduates) to become familiar with ongoing state-of-the-art research work and thus stimulate continued interest in science and engineering. We anticipate that it will reduce by a factor of 20 the current energy consumption (electrical power and cooling water). We expect it to reduce the idle time of the system. And we expect it to provide a state of the art multi-user ultra fast laser facility that will impact research and education efforts throughout our university and those of our collaborators at other institutions.
