The only requirement on pumpbeam aberrations is that the pumpbeam divergence must be less than the phase matching angular tolerance. Some reconversion back into the pumpbeam might have been expected but was not observed. The pumpbeam becomes focused and defocused along the beam axis. The observed asymmetries in the efficiency plots are explained as the result of defocusing of the pumpbeam due to the presence of free electrons. The pumpbeam was highly compressed near the center of the beam, while at the wings; the compression effect was much less. The pumpbeam was highly compressed near the center of the beam, while the compression effect was much less at the wings. It is expected that the nonlinear refractive index effect of the pumpbeam is compensated for by mixing xenon gas. The combined effect of neutral atom depletion and defocusing of the pumpbeam due to the intensity-dependent density of free electrons, significantly modifies the conversion characteristics and efficiency. The first is the observation of only odd harmonics, and the second is the strong dependence of the harmonic intensity on the polarization ellipticity of the pumpbeam. A pulsed pumpbeam can also be multi-passed through the crystal, so that more and more passes pump the crystal.
