Abstract
We report in this paper the first observation of bimodal maser operation in a whispering gallery (WG) mode oscillator. The characteristics of the maser are discussed under operation in both the single and bimodal regimes. A stability measurement of the difference frequency between the maser doublet signals revealed operation for the first time at the fundamental thermal noise limit of the maser.
