Features of optical properties of ferromagnetic semiconductors with dynamic laser-induced gratings
Nonlinear optical phenomena in ferromagnetic semiconductor with dynamic grating created by coherent light beams are investigated. A high-frequency current and nonlinear absorption coefficient are calculated. It is shown that with increasing wave frequency, the nonlinear absorption coefficient grows...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Nonlinear optical phenomena in ferromagnetic semiconductor with dynamic grating created by coherent light beams are investigated. A high-frequency current and nonlinear absorption coefficient are calculated. It is shown that with increasing wave frequency, the nonlinear absorption coefficient grows and reaches the maximum at frequency ω ≈ 3•10¹² s⁻¹, and then smoothly decreases at higher frequencies. Therefore, the second term of the nonlinear absorption coefficient is modulated with coordinate. This proves that a dynamic grating emerges in ferromagnetic semiconductor. |
