摘要：
The second-harmonic generation of 50-fs Ti:sapphire laser pulses in 1- and 2-mm. KDP crystals at 350 mJ of incident energy is measured experimentally and analyzed theoretically. A frequency-conversion efficiency of similar to40% is reached. The limiting influence of self-phase modulation and fundamental phase modulation is demonstrated. The deep modulation of a frequency-doubled spectrum at a high incident intensity is observed. Methods to increase conversion efficiency are proposed. (C) 2004 Optical Society of America.
