Аннотация: Features of Raman gain of probe radiation in three-level atoms placed in a defect of a one-dimensional photonic crystal in the presence of laser radiation (pump) at an adjacent high-frequency transition have been theoretically investigated. It has been shown that there is a pump intensity range where narrow peaks (resonances) simultaneously appear in the transmission and reflection spectra of the probe field. Beyond this region, the peak in the transmission spectrum is transformed to a narrow dip. The spectral position of these peaks is determined by the Raman resonance and the transmittance and reflectance can be larger than unity at pump intensities from several microwatts per square centimeter to several tens of milliwatts per square centimeter. The nature of narrow peaks is due to a sharp dispersion of a nonlinear refractive index near the Raman resonance; this dispersion is responsible for a strong decrease in the group velocity of probe radiation. The proposed scheme makes it possible to obtain controlled ultranarrow resonances in the transmission and reflection spectra of the photonic crystal.

Аннотация: The design of inspection probes for a scanning ferromagnetic resonance spectrometer, which are designed for recording the absorption spectra of electromagnetic energy by local areas of thin magnetic films, is described. The degree of locality is determined by the diameter of the measuring hole of the probe in the range of 0.1–1.0 mm. The sensitivity of the device is significantly increased due to the miniaturization of the heterogeneous measuring resonator and its comparatively high Q factor. A set of replaceable probes makes it possible to cover the frequency range of 0.1–6.0 GHz, the signal-to-noise ratio for a probe with a hole diameter of 0.8 mm, which was measured on a permalloy film with a thickness of 5 nm, is at least 20 dB.
