ON THE PROBLEM OF PULSED OSCILLATIONS IN RUBY MASER

Abstract

IT WAS FOUND THAT THE MECHANISM RESPONSIBLE FOR PULSED OSCILLATIONS IN RUBY MASER IS CONTAINED IN THE PARAMAGNETIC MATERIAL, AND BEARS A CONNECTION WITH ENDOR (electron-nuclear double resonance) interactions existing in ruby. This discovery refutes the theory, commonly held, that the pulsed mode is the result of elementary interaction between the inverted population of the electron-spin system of the paramagnetic substance and the resonant cavity. The pulsed mode of oscillation is accounted for by suggesting that, in the case of the interaction between the electron-spin system and the resonant cavity, the instability producing pulsed oscillations is contained in the spin system. This instability results from the interaction between chromium electrons and distant Al27 nuclei, and effects the pumping rather than the signal transition. (Author)
