摘要：

Clear plateaus, up to the 71st harmonic in Ne and the 69th harmonic in He, were observed in a Ti:sapphire laser, while a gradual decrease to the 25th harmonic in Ne and the 23rd harmonic in He were observed in a KrF laser. High intensity, along with a shorter pulse, induced self-phase-modulation and/or beam breakup in gas media and resulted in the serious degradation or complete disappearance of higher-order harmonics. In the Ti:sapphire laser, the harmonic distribution did not depend on the pulse width of from 120 to 730 fs at a fixed peak intensity.
