Dy 3 (Ga 1 − x Al x) 5 O 12 pseudo-binary single crystals were grown by the Czochralski method. The influence of Al 3+ ions on the spiral bending was investigated. Effective suppression of the spiral symptoms takes place at x = 0.4. In the case of x = 0−0.2 the spiral symptoms were observed in the tail part of crystals. In the case of x = 0.6 there are no spiral symptoms.

Gallium Phosphide (GaP) is one of the few available materials with strong optical nonlinearity and negligible losses in the visible ( >450 )and near-infrared regime. In this work, we demonstrate that a GaP film can generate sub-30 fs (full width at half maximum) transmission modulation of up to ⁓70% in the 600-1000 nm wavelength range.

Gallium phosphide (GaP) is a promising material for nanophotonics, given its large refractive index and a transparency over most of the visible spectrum. However, since easy phase-matching is not possible with bulk GaP, a comprehensive study of its nonlinear optical properties for harmonic generation, especially when grown as thin films, is still missing. Here, …
