Comment on 'The effect of radiation trapping of high-intensity scattered radiation on multiphoton ionisation rates and resonance fluorescence'

Abstract

Recent claims (Salter, ibid., vol.12, p.L763) have been made that the trapping of resonance radiation explains both the efficient ionisation of dense metal vapours irradiated by intense resonant laser radiation and previous experiments concerning anomalous behaviour of resonance fluorescence. The authors examine these claims and show that they are incorrectly developed and that basic physical arguments show that resonance trapping cannot explain the phenomena mentioned above.
