Light-induced atomic desorption dynamics: Theory for a completely illuminated cell
- Zaklad Fizyki, Uniwersytet Rolniczy im. Hugona KollaPtaja w Krakowie, Al. Mickiewicza 21, 31-120 Krakow (Poland)
The light-induced atomic desorption effect, known as LIAD, has been explained so far by a debatable Atutov's theory [S. N. Atutov et al., Phys. Rev. A 60, 4693 (1999)]. In this Brief Report, we propose an approach in which the difficulties of this theory are removed. The theory yields predictions for the atomic vapor density n(t) in a fully illuminated resonance cell, the time t{sub max} that it takes the vapor density to arrive at a maximum value n{sub max} and the dependence of n{sub max} and dn/dt{sub t=+0} on the desorbing light intensity. Some of our results are at variance with outcomes of Atutov's model (such as saturation effect for n{sub max} and the dependence of t{sub max} on the light intensity) but are in agreement with the experimental data. Additionally, the model presented in this Brief Report satisfactorily explains a reservoir effect recently investigated in experiments where cells equipped with a lockable stem were used.
