分子在失调腔中的辐射行为及双腔Maser的振荡现象

本文用量子力学的方法处理了分子在失调腔中的辐射行为。解释了Higa在双腔Maser实验中发现的现象:当第一个腔的频率失调达到某一临界值时,在第二个腔中发生按分子中心频率的突发振荡。求出产生这种突发振荡现象的临界失调公式。也考虑了合作效应的影响。并定性地解释了Страховский等的分子在第二腔中的辐射功率与第一腔频率失调程度的相关性的实验。

ON THE RADIATION OF MOLECULES IN A DETUNED CAVITY AND THE PHENOMENA OF DOUBLE-CAVITY MASERS

The radiation behaviour of the molecules in a detuned cavity has been treated with a more rigorous method of quantum mechanics. The experimental finding of Higa, that when the deutuning of the first cavity reaches a critical value, the second cavity suddenly breaks out into oscillations at the centre frequency of the molecules, is interpreted. A formula is obtained for the critical detuning which leads to the sudden oscillation. The experimental curves obtained by Страховский and Татренков about the dependence of the radiation power of the molecules in the second cavity on the frequency detuning is qualitatively interpreted.
