... Bi-photons are generated in the 1st crystal (12mm long PPKTP), pumped by a single-frequency diode laser at 880 nm with up to 1 W power. Reflection of the bi-photons from mirrors M2 and M3 is accompanied by a spectral phase shift. Both biphotons and pump enter the 2nd identical crystal. The resulting ...
