Second-harmonic conversion efficiencies of 80% for type I KDP crystals and 70% for type II have been demonstrated with 500-fs, 1.053-[mu]m laser pulses at intensities as high as 400 GW/cm[sup 2]. The results are generally in good agreement with simulations and indicate that self-phase modulation and cross-phase modulation may be significant. For type II conversion with a predelay between the input o and e waves, some evidence is obtained of pulse shortening to [similar to]100 fs.
