The clusters generated by direct laser vaporization of KH2PO4 and Cu3(PO4)2 samples are studied by a TOF mass spectrometer. It is found that mainly the [K(KPO3)n] cluster series is generated from KH2PO4 sample and it demonstrates obvious magic numbers, which are n=3, 6, 9, 12, 15. Direct laser vaporization of Cu3(PO4)2 sample produced [Cu(CuPO3)n]4 cluster series as well as other series with the same building block of (CuPO3).
