| Abstract: | Uncertainty in determining the emission angles of the signal and idler photons is investigated. The role of the pump beam divergence, the pump-spectrum width, and the crystal size is elucidated. Experimental data obtained using an intensified CCD camera are in good agreement with a numerical model that provides angular and spectral characteristics of the signal and idler fields. |
