Resonance-Enhanced Multiphoton Ionization of Molecular Oxygen at the 222 nm KrCl Laser Wavelength

We study the photo-ionization mechanism of molecular oxygen at the 222 nm KrCl laser wavelength within a laser pulse intensity range of 10(8) – 10(10) W/cm(2), using 14 ns laser pulses. We experimentally observe (2+1) resonance-enhanced multiphoton ionization (REMPI) of molecular oxygen with the eff...

description We study the photo-ionization mechanism of molecular oxygen at the 222 nm KrCl laser wavelength within a laser pulse intensity range of 10(8) – 10(10) W/cm(2), using 14 ns laser pulses. We experimentally observe (2+1) resonance-enhanced multiphoton ionization (REMPI) of molecular oxygen with the effective ionization cross-section [Formula: see text] = (3.2 ± 1.3) · 10(−18) cm(4) · s(−1) · W(−2) at an intensity range of 10(9) – 10(10) W/cm(2) and linear ionization due to gas impurities at an intensity range of 10(8) – 10(9) W/cm(2).
