摘要：

We report on TOF mass spectrometric analysis of plasmas produced by laser ablation on Al targets, We obtained mass spectra of ionized species in the UV (lambda = 355 nm) and in the visible (lambda = 532 nm) and at high laser fluences (1-80 J cm(-2)). The total ion yield, the relative abundance of different charged species and the laser fluence threshold for the appearance of specific ions as a function of energy density were measured.
