We demonstrate optical resolution photoacoustic microscopy (OR-PAM) of lipid-rich tissue using a multi-wavelength pulsed laser based on nonlinear fiber optics. 1047 nm laser pulses are converted to 1098, 1153, 1215, and 1270 nm pulses via stimulated Raman scattering in a graded-index multimode fiber. Multispectral PAM of a lipid phantom is demonstrated with our low-cost and simple technique.

我们展示了基于非线性光纤的多波长脉冲激光对富含脂质组织的光学分辨率光声显微镜（OR-PAM）成像。1047纳米的激光脉冲通过渐变折射率多模光纤中的受激拉曼散射转换为1098、1153、1215和1270纳米的脉冲。利用我们低成本且简单的技术对脂质模型进行了多光谱光声显微镜成像演示。
