Resumé

Multiphoton detachment of Au- is studied at an irradiation wavelength of 1064 nm and for optical pulses of ~40 ps duration and maximum intensity ~3×1012 W/cm2. The negative gold ion can be detached by absorption of a minimum of two 1.165-eV photons which leads to ejection of ~20-meV electrons. Utilizing a time-of-flight electron spectrometer, the absorption of up to two excess photons is observed with a probability, normalized to the lowest-order peak, of ~5% and ~0.6%, respectively, for first- and second-order excess-photon detachment
