Ultrafast Magnetization Reversal in DyFeCo Thin Film by Single Femtosecond Laser Pulse
Abstract—The possibility of the local all-optical magnetization reversal in a thin ferrimagnetic rare-earth—transition metal film (DeFeCo) by linearly and circularly polarized 35 fs laser pulses is demonstrated e...

Optical Diagnostics of WSe2 Monolayers
WSe2 films have been studied by the method of second harmonic generation (SHG) in the 1200–1420 nm wavelength range at room temperature. Preliminary investigations of photoluminescence spectra and atomic force mi...

Nonlinear optical detection of terahertz-frequency radiation in crystals with periodic domain structure
The temporal and spectral characteristics of the terahertz response are measured for crystals of doped lithium niobate with an as-grown domain structure. It is shown that the crystals can be used for narrow-ba...
