Abstract :
Second-harmonic signals were measured from hyperplastic parenchyma and stroma in malignant human prostate tissue under femtosecond pulsed illumination at different excitation wavelengths. The dependence of the second-harmonic generation on the excitation wavelength provides a possible indicator for recognising tissue components and malignancy.
