A REVIEW OF FE²�?ZNS CRYSTAL

Having said that, this peak at ~978 nm was observed in the two iron-doped and -undoped ZnSe single crystals, and its integrated depth was larger from the iron-undoped sample compared with the iron-doped sample. Thus, we feel that the luminescence peak at ~978 nm is not connected to the emission band involving the doped iron atoms but may well, in i

The gain bandwidth e.g. of Yb:KGW and Yb:KYW is extremely massive compared with that of Yb:YAG. This permits for large wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values very well beneath 100 fs are already attained with passive method locking.The comparison with glasses is acceptable since the sig
