论文摘要
我们对基于全正常分散光子光子晶体纤维的超快超级源源的系统进行了单光束相干反stokes拉曼散射(SB-CARS)光谱测量的改进。基于时间ptychography(i $^2 $ pie)使用新的脉冲重建算法时,出现了对信噪比的改进。一种简单的SB-CARS策略用于测量Para-xylene的光谱,其中使用的超脑脉冲使用多光子Intapulse Intrapulse Intrapulse干扰相扫描(MIIPS)压缩,并且首次使用相同的单个单板设置,这是我们最大程度地压缩的。通过I $^2 $ PIE实施,与MIIP相比,信噪比的靠近派的提高了几乎4倍。更值得注意的是,集成的SB-CARS光谱强度增加了6.5倍。
We present an improvement on the signal-to-background of single-beam coherent anti-Stokes Raman scattering (SB-CARS) spectroscopy measurements for systems employing ultrafast supercontinuum sources based on all-normal dispersion photonic crystal fibers. Improvements to the signal-to-background arise in the use of a new pulse-reconstruction algorithm based on temporal ptychography, I$^2$PIE. A simple SB-CARS strategy is used to measure the spectrum of para-xylene, where the supercontinuum pulses used are compressed using multiphoton intrapulse interference phase scan (MIIPS) and, for the first time to the best of our knowledge, I$^2$PIE using the same single-beam setup. With the I$^2$PIE implementation, the signal-to-background is improved by nearly a factor of 4 in comparison with MIIPS. More notably, the integrated SB-CARS spectral intensity is increased by a factor of 6.5.
