thanks for your reply diazona! apparently A is the probability per unit time of an electron making spotaneous transition so assuming A to be s^{-1} then B should be \frac {m^{3}}{Js^{2}}, http://en.wikipedia.org/wiki/Einstein_coefficients#The_Einstein_coefficients" gives for B \frac {sr...

Homework Statement Hi, I need to know the correct SI units for Einstein Coefficients (A and B) for stimulated emission (say laser). The equation I'm on about is Homework Equations \frac{A}{B} = \frac{8\pi h\nu^{3}}{c^{3}}The Attempt at a Solution after some scribbling I got to \frac{A}{B}...
