RUMORED BUZZ ON PPKTP CRYSTAL

We have now acquired SPDC810 and hoped to use polarization-entangled photons in the beginning. But it seems this unit doesn't have polarization-entangled photons. I'm wondering if you can update/modify our SPDC810 to make it emit entangled photons.The spectral brightness will be the pair-era rate for each optical pump electrical power P for every p
