THE SMART TRICK OF PPKTP CRYSTAL THAT NOBODY IS DISCUSSING

We have now bought SPDC810 and hoped to work with polarization-entangled photons initially. But It appears this device does not have polarization-entangled photons. I wonder if you could possibly update/modify our SPDC810 to really make it emit entangled photons.Could it be attainable to request a slight tuning of the center wavelength from the res

Radiation induced recharging of Ce3+ and Ce4+ ions in Ce and Nd doped yttrium-aluminium garnet crystals was noticed. This effect is dependent upon the Ce3+ ion focus and the kind of ionizing radiation.Increased 2.86 µm emission similar to Ho³�? ⁵I6→⁵I7 was obtained in Nd³�?Ho³�?codoped CaLaGa3O7 crystal for The very first time.
