我们介绍了一个二维电子光谱设置在紫外光谱范围内的部分共线泵浦探测几何。利用被动双折射干涉仪在可见光和非线性相位传输中产生所需的干涉锁相少光周期紫外脉冲对。这是通过锁相可见光脉冲对和窄带红外脉冲之间的和频产生来实现的。我们展示了一对16 fs，330 nm的脉冲，其延迟是干涉稳定的精度优于λ/450。给出了芘溶液在紫外和可见光谱范围内的二维深紫外探测图。(C)2016美国光学学会
We introduce a 2D electronic spectroscopy setup in the UV spectral range in the partially collinear pump-probe geometry. The required interferometrically phase-locked few-optical- cycle UV pulse pair is generated by combining a passive birefringent interferometer in the visible and nonlinear phase transfer. This is achieved by sum-frequency generation between the phase-locked visible pulse pair and narrowband infrared pulses. We demonstrate a pair of 16-fs, 330-nm pulses whose delay is interferometrically stable with an accuracy better than lambda/450. 2DUV maps of pyrene solution probed in the UV and visible spectral ranges are demonstrated.
