论文摘要
泵探针显微镜是一种基于高重复速率激光器和快速强度调制的新兴非线性成像技术。在这里，我们提出了泵探针显微镜的新方法，该方法可以使光束强度保持恒定并调节脉冲间的时间延迟，相对极化或脉冲长度。这些技术可以改善散热不良或长寿命辐射状态的样品的图像质量，并且可以选择性地解决样品中的非线性相互作用。我们通过实验证明了这种方法，并指出了比常规强度调制的优势。
Pump-probe microscopy is an emerging nonlinear imaging technique based on high repetition rate lasers and fast intensity modulation. Here we present new methods for pump-probe microscopy that keep the beam intensity constant and instead modulate the inter-pulse time delay, the relative polarization, or the pulse length. These techniques can improve image quality for samples that have poor heat dissipation or long-lived radiative states, and can selectively address nonlinear interactions in the sample. We experimentally demonstrate this approach and point out the advantages over conventional intensity modulation.
