摘要：

Harmonic generation is investigated at an intensity range of 10(15)-10(18) W/cm2 by using a 280-fsec KrF laser. The highest-order harmonic observed with Ne as a nonlinear medium is the 25th (9.9 nm), which gives the shortest-wavelength coherent radiation ever obtained. The inversions or anomalous peaks of harmonic intensity are first found at the 19-21st in Ne, the 17-19th in He, and the 11-13th in Ar. The intensity dependence of the harmonics is measured over arrange of 10(15)-10(18) W/cm2. The observed distribution of harmonics is discussed and compared with the previous reports.
