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.

该提案是为资金购买额外的设备，以增加目前的钛：蓝宝石激光系统的应用在泵/探针和简并四波混频（DFWM）配置。 所要求的设备将允许开发一种基于皮秒、锁模激光器的诊断，这种诊断将有可能获得高频湍流统计数据，观察快速瞬态事件，并通过在非常短的时间尺度上测量物质浓度和温度来分析湍流燃烧室的稳定性行为。 应尽量减少碰撞的影响。
