| Abstract: | Multiphoton ionization coefficients of atmospheric gases were measured with ultrashort ultraviolet laser pulses. The values were obtained using two different experimental setups and the pressure range covered four orders of magnitude. The coefficients were pressure-independent and consistent with numbers predicted by the nonresonant Keldysh theory.
