摘要：

We have experimentally demonstrated the generation of a powerful femtosecond pulse at 264 nm, starting with a picosecond pulse from a Nd:glass laser and using a nonlinearly compressed second-harmonic pulse. Fourth-harmonic pulses with durations between 130-370 fs have been generated in KDP and BBO crystals of various lengths. The consistency of the numerical and experimental data indicates that group-velocity mismatch and two-photon absorption are the main factors limiting the efficiency of the frequency quadrupling process with femtosecond pulses.
