摘要: We study the photodetachment of H{sup -}, F{sup and Br{sup -} in a short laser pulse 800 nm wavelength 6x10{sup 14} W/cm{sup 2} peak intensity. Photoelectron spectra, recorded with use an imaging technique, reveal substantial contribution from sequential process double detachment halogen negative ions. The saturation effect is shown to play crucial role this process. alignment atoms produced by discussed.
