    I Tips on generating entangled photon pair with SPDC entanglement source

    Hello PokemanDude, Questions, 1. Do you see some lasers generated by the parametric process at signal wavelength and idle wavelength? If you do see some lasers, it means the alignment process should be OK. 2. If you do see some lasers generated by parametric process, can you test the...
