    Can anyone briefly explain that what is saturated absorption? What's the condition to have saturated absorption?

    I've never heard the term before, but I suspect it means a process where a 50-50 distribution has already been reached (by this I mean that both states involved in the process are equally populated), meaning the system can not absorb more energy.

    This is also known as "Hole burning" in optics.
