Engineering Research Equipment Grant: Pulsed Dye Amplifier and CW Dye Laser Upgrade

该工程研究设备补助金将支持购买能够产生窄线宽（100 MHz）或短时间宽度染料激光脉冲的设备。特别需要的是一种脉冲染料放大器（PDA），它可以实现涉及双原子分子的各种光谱实验，这些分子是新的VUV， UV或可见激光器的有吸引力的候选者。同时，现有的连续波染料激光器将升级为窄线宽、扫描操作。这两种设备将与现有的泵浦激光器（PDA的准分子，CW染料的AR+离子）相结合，通过光谱来检查结构：(1)稀有气体二聚体（用于VUV中潜在的反斯托克斯拉曼激光器）；(2)稀有气体氧化物；(3)碘化铅。此外，还将进行旨在探索量子阱半导体激光器脉冲放大的实验。该设备将提高研究潜在新激光分子的结构和化学行为细节的能力，并在VUV中开发新的可调谐辐射源，以及扩大其他正在进行的研究的范围。

This Engineering Research Equipment Grant will support purchase of equipment capable of producing narrow linewidth ( 100 MHz) or short temporal width dye laser pulses. Specially, a pulsed dye amplifier (PDA) is sought which would enable a variety of spectroscopic experiments involving diatomic molecules that are attractive candidates for new VUV, UV or visible lasers. Also an existing CW dye laser will be upgraded to narrow linewidth, scanning operation. Both of these items of equipment will be coupled with existing pump lasers (excimer for the PDA, AR+ ion for the CW dye) to examine the structure via spectroscopy of: (1) rare gas dimers (for a potential anti-Stokes Raman laser in the VUV); (2) rare gas oxides; and (3) lead monoiodide. Furthermore, experiments designed to explore the pulsed amplication of quantum well semiconductor lasers will be conducted. This equipment will improve the ability to investigate the details of the structure and chemical behavior of potential new laser molecules and develop new sources of tunable radiation in the VUV to visible, as well as expand the scope of other on-going research.
