Abstract

We report a versatile setup based on the femtosecond adaptive spectroscopic techniques for coherent anti-Stokes Raman scattering. The setup uses a femtosecond Ti:Sapphire oscillator source and a folded 4f pulse shaper, in which the pulse shaping is carried out through conventional optical elements and does not require a spatial light modulator. Our setup is simple in alignment, and can be easily switched between the collinear single-beam and the noncollinear two-beam configurations. We demonstrate the capability for investigating both transparent and highly scattering samples by detecting transmitted and reflected signals, respectively.

摘要

我们报道了一种基于飞秒自适应光谱技术的用于相干反斯托克斯拉曼散射的通用装置。该装置使用飞秒钛宝石振荡器源和折叠式4f脉冲整形器，其中脉冲整形通过传统光学元件进行，不需要空间光调制器。我们的装置对准简单，并且可以很容易地在共线单光束和非共线双光束配置之间切换。我们分别通过检测透射和反射信号，展示了研究透明和高散射样品的能力。
