Subject: In the energy level diagram of lasers the energies are marked in +ve value

The energy level diagrams in general should be negative as per the derivation of
energy of nth orbit. then how is this possible? Pl provide me with a better
answer .I'm really impressed by yr service and also my previous question is
recorded in your website. I hope for a quick reply.
