摘　　要：对不同载体上不同沾染物的指纹印迹特征用410～710nm可调谐激光进行荧光再现，再用滤色片将激光滤除，从而摄取清晰的指纹印迹荧光照片。In this paper, we obtained the visible range wide band (410 -- 710nm ) of the optical parametric generation and amplifier in ps BBO that has been used in identifying the criminals fingerprint. The fingerprint of different contaminator and secretion in different carrier can be reappeared by illuminating of different wavelength laser beam. Separated off laser light with the optical filter, the photographs of clear fingerprint -- fluorescence picture were shown and compared by laser light and natural light.
