NOT KNOWN FACTS ABOUT CO²�?/ZNS CRYSTAL

We acquired few-optical-cycle pulses having a multi-Watt common energy in a very wide number of repetition fees 0.07–one.2 GHz. We also report on economical nonlinear frequency conversion straight in the polycrystalline get things of extremely-fast lasers and amplifiers such as second harmonic generation with sub-Watt energy and era of an octave-
