59 o Figure 40-24 shows the energy levels of two types of
atoms. Atoms A are in one tube, and atoms B are in another tube.
The energies (relative to a ground-state energy of zero) are
indicated; the average lifetime of atoms in each level is also indi-
cated. All the atoms are initially pumped to levels higher than the
levels shown in the figure. The atoms then drop down through the
levels, and many become "stuck" on certain levels, leading to popu-
lation inversion and lasing. The light emitted by A illuminates B
and can cause stimulated emission of B. What is the energy per
photon of that stimulated emission of B?
