High-order harmonic radiation with noble gas and N〓 in static gas target has been obtained, and the effects on high-order harmonic efficiencies due to laser intensities , polarization, gas densities, confocal parameter, media characteristic and phase mismatch have been discussed. The experimental results show that the high-order intensities grow with the incident laser intensities and gas densities, and high-order harmonic signals amplify in the same time.
