Estimate the ratio of the rate of stimulated to spontaneous emission at three wavelengths: (a) 12 cm, in the microwave (b) 5x10-4 cm, in the mid-infrared, and (c) 7x10-5 cm, in the ultraviolet. Assume a blackbody source (see Hollas p. 39) at 300 K. (d) Discuss the implications of the results determined in parts (a)-(c) for the following applications: fluorescence spectroscopy, excited state lifetime measurements (the lifetime of the excited state is inversely proportional to the Anm coefficient), and lasers (hint: what does it stand for
