The property of the spontaneous parametric downward conversion (SPDC) light spec-trum distribution was analyzed theoretically ,and the field distribution of the type Ⅱ SPDC light gen-erated in BBO crystal pumped by a 403 nm continuous laser was given by numerical simulation .A photon (of the wavelength of 806 nm ,created by SPDC) distribution measurement apparatus was also designed .The experimental results were in accordance to the simulation .
