Cross-beam Nonlinear Photoacoustic Microscopy


We present a cross-beam nonlinear photoacoustic microscopy (PAM) technique that enhances the axial resolution. By combining cross-beam illumination with optical nonlinearity, an axial resolution of 8.7 µm is measured experimentally, a fourfold improvement over the acoustically determined value.
