Pulsed laser with OPO

反应机理的研究需要脉冲源来产生中间体。本提案中描述的激光器将用于产生化学物质，然后使用快速光谱学进行研究。它将补充现有的准分子激光器，提供足够的波长灵活性。所要求的激光器类型，包括光学参量振荡器（OPO）允许波长灵活性;目前OPO系统提供了比染料激光器（过去广泛使用）更容易和更可靠的光源。 这是研究许多反应机制以及纳米材料的重要工具，这是我们目前研究的重点。这些工具将允许选择性激发纳米材料，如金属纳米颗粒。

The study of reaction mechanisms requires pulsed sources for the generation of intermediates. The laser described in this proposal will be used to generate the chemical species that will be then studied using fast spectroscopy. It will complement existing excimer lasers in providing adequate wavelength flexibility. The type of laser requested, incorporating an optical parametric oscillator (OPO) allows wavelength flexibility; at present OPO systems offer an easier and more reliable source than dye lasers (widely used in the past).  This is an essential tool for the study of many reaction mechanisms, as well as nanomaterials, an area emphasized in our current research. These tools will allow the selective excitation of nanomaterials, such as metal nanoparticles.
