Abstract

We present, for the first time, the complete pulse characterization of the infrared pulse after generating harmonics. A systematic study of the high harmonic generation process, and the generating infrared pulse characterization, has been done by changing the focus-gas-jet relative position. We have concluded, supported by nonlinear propagation simulations, that there is a correlation between the spectral and temporal nonlinear evolution of the infrared generating field and the structures shown in the harmonic signal. We have identified two different pressure regimes: the low pressure regime, characterized by the effects produced by the plasma generated by the infrared pulse, and the high pressure regime where the plasma and the Kerr effect generated by the infrared field are both present. These observations highlight the important role played by the nonlinear propagation of the generating field in the high harmonic generation context.

  20. We estimate the intensity at the focus by doing linear Gaussian propagation. This estimation is clearly overestimating the intensity because assume perfect Gaussian spatial shape, aberration free focusing and linear propagation. Any of this effects will deteriorate the focusing process producing a bigger focal spot and a lower intensity.
