Before you start learning PBM calculations be aware that Joules and J/cm2 are not a good way to express dose. You should ideally read the following paper first and come on a THOR training course.

This paper from Harvard Medical School reviews the PBM mechanisms and the biphasic dose response. It summarises the molecular and cellular mechanisms of PBM, gives a scientific explanation for the biphasic dose response (why a low dose has a stimulatory effect and why a high dose inhibits). Low power densities tend to get better healing and anti-inflammatory effects where higher power densities are more likely to inhibit (which may be useful if you just want an analgesic effect). I have to disclose an interest in this paper because I am a co-author. James Carroll CEO THOR Photomedicine.
