The direct accurate measurement of local OH concentrations has been one of the major technical challenges in atmospheric chemistry since the early 1980s. This goal was first achieved in the stratosphere (e.g., Stimpfle and Anderson, 1988), but the troposphere proved more difficult (Crosley, 1995). Nevertheless, early long-baseline absorption methods for OH were adequate to test some basic theory (e.g., Poppe et al., 1994). Current successful direct methods include differential optical absorption near-UV spectroscopy with long baselines (e.g., Mount, 1992 Dorn et al, 1995 Brandenburger et al., 1998), laser-induced fluorescence after expansion of air samples (e.g., Hard et al., 1984, >1995 Holland et al., 1995), and a variety of chemical conversion techniques (Felton et al, 1990 Chen and Mopper, 2000 Tanner et al., 1997).

As in so many other fields, advances in measurement, in this case submicrometer particle sizing using laser light scattering, only became a reality when suitable technology became available to exploit the basic theories and mathematics that were already available.

Judd (1962) and Ofelt (1962) independently derived expressions for the oscillator strength of induced electric dipole transitions within the f configuration. This was a signal accomplishment. Much of the highly significant theoretical interpretation of the fluorescence process and the prediction of the properties of solid state lanthanide lasers, ch. 35, was made possible by this work. Since their results are similar, and were published simultaneously, the basic theory has become known as the Judd-Ofelt theory. However, Judd s expression, eq. (24.6), was cast in a form that could be directly related to oscillator strengths derived from lanthanide solution spectra, and he was the first to show that the model satisfactorily reproduced the experimental results for Nd (aquo) and... 

In the case of nonrelativistic laser intensity, linear theory does not allow propagation in overdense plasmas, namely when to 1 < iop(. = e(An/rn,.) 2n,J 2. In the extreme case of ultra-relativistic laser intensity (ao 2> 1), the cutoff frequency for propagation drops from u pe down to wpe/(l Tag)1/4 [11], where ao = eA/mec is the dimensionless amplitude of the laser field. Then, in order for the propagation to occur at plasma density appreciably higher than the ordinary critical density, ao 2> 1 is needed. This is also the case of overdense thin plasma layers (as proved by simulation [12]) whose thickness exceeds the skin penetration depth of the e.m. wave. Theoretical background and basic...
