Main Question or Discussion Point
Hello! I have seen mentioned in several papers the concept of power broadening, which (if I understand it right) means that the linewidth of a transition (say, in an atom) get wider with increasing the power of the laser used (even if the linewidth of the laser is kept constant). I am not totally sure I understand the physics behind it. Can someone explain it to me or point me towards some accessible readings on this topics (preferably not actual papers, maybe a book or something easier as a first reading). Thank you!
