我们首次观测到由亚皮秒KrF准分子激光激发的类稀有气体离子的高次谐波。在光强为10(15)W/cm2时，观察到的最高谐波为Li+的第9次(27.6 nm)、Na+的第11次(22.6 nm)和K+的第13次(19.1 nm)。从电离势的角度讨论了这类离子作为非线性介质产生极紫外光的优势。
We report the first observation of high-order harmonic waves from rare-gas-like ions excited by a sub-picosecond KrF excimer laser. At an intensity of 10(15) W/cm2, the highest orders of observed harmonics are the ninth (27.6 nm) in Li+, the eleventh (22.6 nm) in Na+, and the thirteenth (19.1 nm) in K+. The advantage of such ions as nonlinear media for extreme ultraviolet generation is discussed in relation to ionization potentials.
