11. The induced emission comes from the pumping procedure and then is added to the spontaneous emission . 12. Instead of masturbation, Hall viewed spontaneous emissions as a natural and acceptable alternative to forced ejaculation. 13. For example, the spontaneous emission rate and behaviour of atoms is altered by such a microcavity. 14. Some technical terms for related processes include Atomic absorption spectroscopy, Compton scattering, spontaneous emission , stimulated emission. 15. Thus, the rate of transitions between two stationary states is increased beyond that of spontaneous emission . 16. So the output power depends linearly on the spontaneous emission rate and exponentially on the optical gain. 17. The theory of the spontaneous emission under the QED framework was first calculated by Weisskopf and Wigner. 18. Thus, the rate of transitions between two stationary states is enhanced beyond that due to spontaneous emission . 19. This prevents amplified spontaneous emission and is important for a good beam quality and high power amplifiers. 20. Depopulation by spontaneous emission is very important as well as reactions ( 11 ) and ( 17 ).
