摘　　要：Twin photon generation at various emission angles is observed. It is found that different kinds of twin photons using only one crystal under different conditions are obtained. Twin photon generation is more effective at smaller emission angles. Two-photon entanglement is also achieved after compensation.Twin photon generation at various emission angles is observed.
