Stimulated emission per second per atom?

[QUOTE="Cutter Ketch, post: 6046891, member: 515910"] Finding B as you describe is fine. Planck’s radiation law which you show will also be necessary. You are almost there. What is B good for? How is it used? Do you perhaps see it in a differential equation relating the rate of stimulated emission to the upper state population density? What must be the units of the coefficient on the upper state population density? [/QUOTE]
