This award from the National Scientific Foundation Major Research Instrumentation program supports the acquisition of a phase stabilized optical frequency comb by the University of Nevada, Las Vegas (UNLV). The optical frequency comb (OFC) enables a broad range of research activities in the Departments of Physics, Chemistry, Electric engineering, and Geoscience. The instrument will expand research capabilities and ignite collaboration between 15 faculty at UNLV and roughly 50 of their associated students and postdocs. The equipment will be a cornerstone toward building a research center for exploring new methods and technologies in quantum sensing and information processing, connecting expertise in AMO physics, condensed matter physics, physical chemistry, electric engineering, and geoscience. This instrument will enable investigations of fundamental questions in science and engineering, advance the training of the diverse graduate and undergraduate STEM students at UNLV, and increase the skilled workforce available in the Southern Nevada area and the desert Southwest. The requested OFC will be the first advanced light source facility with extreme coherence and broad bandwidth in Nevada. Thus, installation of the requested instrument within a UNLV research core will enhance the capabilities of Southern Nevada economic development in quantum science, novel materials, and astrophysical and geological explorations. This project is jointly funded by the MPS (Mathematical and Physical Sciences) Directorate, the Physics (PHY) Division, the Established Program to Stimulate Competitive Research (EPSCoR), and the Office of Integrative Activities (OIA).The OFC is the newest generation of light sources that combines accurate phase information (approximately 1 part per 10^20) in the frequency-domain and ultrafast temporal information (femtoseconds) in the time-domain simultaneously. It has been used as a precision optical frequency synthesizer to explore new phenomena in fundamental science and is a crucial component in the world's most precise atomic clock (Nobel Prize in Physics, 2005). Besides exhibiting an ultrabroad spectroscopic coverage and narrow linewidth, the OFC revolutionizes molecular spectroscopy with unprecedented speed and sensitivity, having already enabled successful applications in physics, chemistry, and environmental science. The OFC at UNLV will enable the following detailed studies: (1) development of a new generation of quantum sensors facilitating exploration of new physics beyond the Standard Model; (2) investigations of quantum computation platforms (photon, ion, superconducting circuit) and construction of a quantum network between them; (3) utilization and extension of novel asynchronous sampling pump-probe spectroscopy by dual-OFC in various studies in condensed matter physics and chemistry, such as probing driven topological phases in 2D systems and ultrafast photochemistry under high pressure; (4) study of novel synthesized materials, such as room-temperature superconductors (RTSC) by efficient nonlinear spectroscopy; (5) exploration of interstellar chemistry by performing broadband, high-resolution spectroscopy of cold molecules and probing ion-radical cold collisions; (6) study of radiochemistry by high resolution spectroscopy of molecules containing heavy elements; and (7) development of new technology for determining elemental abundances in solid rock samples.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项来自国家科学基金会主要研究仪器计划，支持内华达大学拉斯维加斯分校 (UNLV) 购买相位稳定光学频率梳。光学频率梳 (OFC) 支持物理、化学、电气工程和地球科学系的广泛研究活动。该工具将扩大研究能力，并激发 UNLV 15 名教员与大约 50 名相关学生和博士后之间的合作。该设备将成为建立研究中心的基石，探索量子传感和信息处理的新方法和技术，连接AMO物理、凝聚态物理、物理化学、电气工程和地球科学的专业知识。该仪器将能够研究科学和工程的基本问题，促进内华达大学拉斯维加斯分校多样化研究生和本科生 STEM 学生的培训，并增加内华达州南部地区和西南部沙漠地区的熟练劳动力。所要求的 OFC 将成为内华达州第一个具有极高相干性和宽带宽的先进光源设施。因此，在内华达大学拉斯维加斯分校研究核心内安装所需的仪器将增强内华达州南部在量子科学、新型材料以及天体物理和地质勘探方面的经济发展能力。该项目由 MPS（数学和物理科学）理事会、物理 (PHY) 部门、刺激竞争研究既定计划 (EPSCoR) 和综合活动办公室 (OIA) 联合资助。OFC 是最新一代同时结合频域中的精确相位信息（大约每 10^20 1 部分）和时域中的超快时间信息（飞秒）的光源。它已被用作精密光学频率合成器来探索基础科学中的新现象，并且是世界上最精确的原子钟的重要组成部分（2005年诺贝尔物理学奖）。除了具有超宽光谱覆盖范围和窄线宽之外，OFC 还以前所未有的速度和灵敏度彻底改变了分子光谱学，已在物理、化学和环境科学领域取得了成功的应用。 UNLV 的 OFC 将实现以下详细研究：（1）开发新一代量子传感器，促进对标准模型之外的新物理的探索； （2）量子计算平台（光子、离子、超导电路）的研究以及它们之间的量子网络的构建； (3) 双 OFC 新型异步采样泵浦探针光谱在凝聚态物理和化学的各种研究中的利用和扩展，例如二维系统中探测驱动的拓扑相和高压下的超快光化学； （4）通过高效非线性光谱研究新型合成材料，例如室温超导体（RTSC）； (5) 通过对冷分子进行宽带、高分辨率光谱和探测离子-自由基冷碰撞来探索星际化学； (6)通过含重元素分子的高分辨率光谱研究放射化学； (7) 开发确定固体岩石样品中元素丰度的新技术。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
