This is an instrument acquisition award from the Major Research Instrumentation program and the Instrumentation for Materials Research program to the City University of New York Queens College. The award will allow CUNY Queens College to purchase a Coherent 899-29 Autoscan II single frequency scanning laser for the study of the statistics of optical propagation in random and nearly periodic materials and photonic devices. The instrument will allow the principal investigators to extend the coherent technique developed in the microwave region of the spectrum to visible and infrared frequencies. It will allow them to characterize the statistics of transport using statistical measures of the transmitted fields and intensity, and to use the variance of intensity fluctuations as a sure test of phonon localization free of ambiguities arising from absorption of microwave resonance. Band edge and localized modes in cholesteric liquid crystals will be characterized. The objective is to clarify the conjunction of lasing and localization and guide development of homogeneous cholesteric materials in which ultra-low lasing threshold will be observed. The instrument will provide students preparing for careers in physics with a sound mix of microwave and optical techniques as well as exposure to industrial research laboratories engaged in forefront research.

这是一个仪器采购奖从主要研究仪器计划和仪器材料研究计划的纽约皇后学院城市大学。该奖项将允许纽约市立大学皇后学院购买相干899-29 Autoscan II单频扫描激光器，用于研究随机和近周期材料和光子器件中的光传播统计。该仪器将使主要研究人员能够将在微波频谱范围内开发的相干技术扩展到可见光和红外频率。这将使他们能够使用传输场和强度的统计测量来表征传输的统计数据，并使用强度波动的方差作为声子定位的可靠测试，而不受微波共振吸收引起的模糊性的影响。 研究了双折射液晶的带边模和局域模。其目的是阐明激光和局域化的联系，并指导观察到超低激光阈值的均匀胆甾材料的开发。该仪器将为准备从事物理学职业的学生提供微波和光学技术的合理组合，以及接触从事前沿研究的工业研究实验室。 这是一个仪器采购奖从主要研究仪器计划和仪器材料研究计划的纽约皇后学院城市大学。该奖项将允许纽约市立大学皇后学院购买相干899-29 Autoscan II单频扫描激光器，用于研究随机和近周期材料和光子器件中的光传播统计。该仪器将使主要研究人员能够将在微波频谱范围内开发的相干技术扩展到可见光和红外频率。该仪器将为准备从事物理学职业的学生提供微波和光学技术的合理组合，以及接触从事前沿研究的工业研究实验室。
