What it actually means is, that if an initial fluence of, say, 10 J/cm2, is applied to the skin surface, then it will reach a maximum value of 23 and 20 J/cm2 for 755nm and 1064nm, respectively, at the top of the dermis.
These fluences will drop back to the original value at the depth of 1.5mm.
Conclusion
This model data is quite counter-intuitive. But that’s simply because we don’t tend to think of photons ‘turning around’ inside the skin and moving back towards the surface!! Once you understand that, then this data becomes much more sensible.
I am using this to calculate the optimum fluences needed for the removal of hair follicles and blood vessels.
I’ll keep you posted...
Ciao for now, Mike.
