ENGINEERING RESEARCH EQUIPMENT: Picosecond Diagnostics in Reacting Flows Using a Mode-Locked Ti:Sapphire Laser

这项提议是为购买额外的设备，以增强现有的钛宝石激光系统，用于泵浦/探测和简并四波混频(DFWM)配置。所要求的设备将允许开发基于皮秒锁模激光的诊断，这将使获得高频湍流统计数据、观察快速瞬变事件以及通过在很短的时间尺度上测量物种浓度和温度来分析湍流燃烧室的稳定性行为成为可能。应将碰撞的影响降至最低。

This proposal is for funds to purchase additional equipment to augment a present Ti: Sapphire laser system for applications in a pump/probe and degenerate four wave mixing (DFWM) configurations. The requested equipment will allow the development of a picosecond, mode locked laser based diagnostic which would make it possible to obtain high frequency turbulence statistics, to observe rapid transient events, and to analyze stability behavior of turbulent combustors through the measurement of species concentration and temperature on a very short time scale. The effects of collisions should be minimized.
