Simultaneous Measurement of Two Arbitrary Ultrashort Laser Pulses Using Double-Blind Frequency Resolved Optical Gating

小行星9361715 我们建议开发一种仪器，它将完全表征（测量强度和相位）两个超短激光脉冲同时，最终在一个单一的拍摄，这将有利于低能量超短脉冲的测量，有助于表征超短激光系统，也将允许子脉冲动力学解决。 该设备基于一种新发明的技术，用于测量超短光脉冲的强度和相位，称为频率分辨光学门控（FROG）。 然而，所提出的技术不是使用脉冲经由光学克尔效应来选通自身，而是使用未知脉冲来选通不同的未知脉冲。 像FROG一样，选通脉冲在一系列时间延迟下进行光谱解析。 这两个脉冲的强度和相位是通过使用二维相位检索方法，通常用于天文学和图像处理去模糊图像。 该设备不仅可以测量脉冲，还可以提供对超快激光操作的洞察，从而使它们更容易，更有效地使用。 直接的商业应用是针对用作诊断现有的超快激光系统，目前很少有。 未来的商业应用包括用作工业、学术界和政府的研究工具。 *** v S t $ $ $ ( F / H H / 1件 Symbol Arial 5 Cash New h C C C " H YB % C C R:\WW20USER\ABSTRACT.DOT 丹尼斯亨利丹尼斯亨利

9361715 Kane We propose to develop an instrument that would completely characterize (measure the intensity and phase) two ultrashort laser pulses simultaneously, ultimately in a single shot, which would facilitate measurement of low energy ultrashort pulses, help to characterize ultrashort laser systems, and would also allow sub-pulse dynamics to be resolved. The proposed device is based on a newly invented technique to measure the intensity and phase of ultrashort light pulses called frequently-resolved optical gating (FROG). However, rather than use the pulse to gate itself via the optical Kerr effect, the proposed technique uses an unknown pulse to gate a different unknown pulse. Like FROG, the gated pulse is spectrally resolved for a series of time delays. The intensity and phase of both pulses is found by using two-dimensional phase retrieval methods that are commonly used in astronomy and image processing to deblur images. This device would not only measure pulses, but would provide insight into ultrafast laser operation as well and hence allow them to be used more easily and more effectively. Immediate commercial applications are directed toward use as a diagnostic for existing ultrafast laser systems for which few are currently available. Future commercial applications include use as research tool for industry, academia, and government. *** v s t $ $ $ ( F / h h / 1 Courier Symbol & Arial 5 Courier New h c c c " h YB %YB % c C R:\WW20USER\ABSTRACT.DOT Denise Henry Denise Henry
