Abstract

The relative narrowness of the bandwidth of masers limits the field of their practical application. In order to overcome this shortcoming, the most frequency practice is to use the method of magnetic detuning of the active crystal in the amplifier (see [1]). The latter method was proposed for expanding the passband of a traveling-wave maser, but it is also applicable to resonator masers in the case when the magnetic Q of the active substance is significantly lower than the Q of the ESR line (see [2]).

Below we consider the possibility of compensating the shape of the amplitude-frequency response of a magnetically detuned maser and the additional broadening of its passband by altering the shape of the active crystal.
