Role of the plasma scale length in the harmonic generation from solid targets
We have investigated the generation of high harmonics from the interaction of 150 fsec, 790 nm, and 395 nm laser pulses with solid targets. Experiments are presented that demonstrate a strong dependence of the conversion efficiency on the temporal pulse shape and the resulting density scale length (...

| description | We have investigated the generation of high harmonics from the interaction of 150 fsec, 790 nm, and 395 nm laser pulses with solid targets. Experiments are presented that demonstrate a strong dependence of the conversion efficiency on the temporal pulse shape and the resulting density scale length (L/λ) of the preformed plasma. The highest conversion efficiencies are achieved for short density scale lengths (L/λ ≤ 0.4), which result from high contrast ratio pulse interactions. |
