Fig. 3: Maser emission spectrum.
From: Maser threshold characterization by resonator Q-factor tuning
a Maser emission power \(\left\vert {A}_{{{{{{{{\rm{M}}}}}}}}}\right\vert\), in logarithmic units, as a function of frequency and static magnetic field at wL = 430 s−1 and QL of about 33,500. b \(\left\vert {A}_{{{{{{{{\rm{M}}}}}}}}}\right\vert\) as a function of frequency for two different magnetic field values, indicated by the red and green dashed lines in (a).
