Data for the dissociation and ionisation of NO2 with laser intensities up to 2.3 × 1014 W cm-2 are presented. The effects of variation in intensity, wavelength and pulse width are discussed. For 90 fs pulse width the relative parent-ion yield is independent of the laser intensity at 750 nm but shows a weak dependence at 375 nm. The parent-ion yield is observed to increase as the laser pulse width decreases. The longer wavelength of 750 nm produces a larger parent-ion yield in comparison with 375 nm. This would suggest that pulse width and laser wavelength are important parameters in short-pulse laser mass spectrometry. © 1998 Elsevier Science B.V. All rights reserved.
