Nonlinear modes of operation of a quasioptical resonator with the paramagnetic layer
Alexey A. Vertiy
Experimental investigations of nonlinear characteristics of the transfer coefficient (G) and bistability phenomena in a quasioptical resonator with the ruby layer saturated under the electron spin resonance conditions (ESR) are presented. Experiments have been carried out on the special radiophysical complex BURAN /1/ at the electromagnetic wave frequency ν = 75⋅109H3 and in the temperature range T = 0.9 K + 4 K and with the static magnetic field H<6 T. A two-mirror half-symmetric open resonator has the mirror aperture about 2a=8λ, the radius of a spherical mirror R = 15λ , the quality factor Q ≈8⋅103 and operates on the spectral mode TEM0011. A ruby layer (thickness h = λ/4) is placed near the plane mirror.
