我们介绍飞秒宽场瞬态吸收显微镜相结合的子10 fs的泵和探测脉冲覆盖完整的可见光(500-650 nm)和近红外(650-950 nm)光谱与衍射限制的光学分辨率。我们证明了我们的系统的能力,通过报告的空间和光谱分辨瞬态电子响应MAPbI 3-xClx钙钛矿薄膜,并揭示显着淬火的瞬态漂白信号在晶界。前所未有的时间分辨率使我们能够直接观察到带隙重整化的形成,在光激发后25 fs完成。此外,我们获得高光谱拉曼地图的TIPS并五苯薄膜与子-400 nm的空间和子-15 cm-1的光谱分辨率覆盖100-2000 cm-1的窗口。我们的方法开辟了在各种二维和纳米系统中研究纳米长度和飞秒时间尺度上的超快动力学的可能性。
We introduce femtosecond wide-field transient absorption microscopy combining sub-10 fs pump and probe pulses covering the complete visible (500–650 nm) and near-infrared (650–950 nm) spectrum with diffraction-limited optical resolution. We demonstrate the capabilities of our system by reporting the spatially- and spectrally-resolved transient electronic response of MAPbI3–xClx perovskite films and reveal significant quenching of the transient bleach signal at grain boundaries. The unprecedented temporal resolution enables us to directly observe the formation of band-gap renormalization, completed in 25 fs after photoexcitation. In addition, we acquire hyperspectral Raman maps of TIPS pentacene films with sub-400 nm spatial and sub-15 cm–1 spectral resolution covering the 100–2000 cm–1 window. Our approach opens up the possibility of studying ultrafast dynamics on nanometer length and femtosecond time scales in a variety of two-dimensional and nanoscopic systems.
