Optical nonlinear characteristics of MgF₂ films containing Cu nanoparticles

【摘要】 <正> An investigation is made on the optical nonlinear characteristics of MgF₂ films containing Cu nanoparticles.When the Cu volume fraction is 0.1,at approximately ε_m + 2ε_d = 0,the film exhibits a strong thirdorderoptical nonlinear refractive coefficient of 1.0×10^-9 cm²/W,a nonlinear refractive index of about-4.0×10^-7 esu,a third-order optical nonlinear response of about 6.8×10^-8 esu,and a figure of meritof about 1.0×10^-11.The result shows that the film may have potential applications in optoelectronictechnology.更多还原

When the Cu volume fraction is 0.1,at approximately ε_m + 2ε_d = 0,the film exhibits a strong thirdorder optical nonlinear refractive coefficient of 1.0×10^-9 cm²/W,a nonlinear refractive index of about -4.0×10^-7 esu,a third-order optical nonlinear response of about 6.8×10^-8 esu,and a figure of merit of about 1.0×10^-11.The result shows that the film may have potential applications in optoelectronic technology.更多还原
