Abstract:

The equations are generalized governing coherent emission from quantum mechanical amplifiers microwave, infrared, and optical masers using either electric or magnetic dipole transitions. Earlier analyses by Gordon, Zeiger and Townes, Feynman, Vernon and Hellworth, and Wang and Singer, are incorporated in this generalization. The principal new result of this analysis is that an amplitude modulation of the output is to be expected from all maser oscillators excepting those in which excited atoms are supplied at a notably greater rate than the depopulation rate due to coherent induced emission. This analysis also suggests that an energy population inversion of electric dipole moments can be performed using coherent light sources in the same manner as with magnetic dipole moments. It appears therefore that modulation of an optical or infrared maser e.g., for communication purposes may be easily accomplished by varying the population of excited states through control of the pumping energy. This modulation may be both by absorption and amplification. Author
