Abstract AR
في هذا البحث تم حساب معامل الانكسار و الامتصاص اللاخطي لمحلول مائي لصبغه روس بنغال باستخدام تقنيه المسح باتجاهZ للفتحة المغلقة و المفتوحة و لنفس الطول الموجي.
لقد وجد أن معامل الانكسار اللاخطي لهذه الصبغة يظهر صفات لاخطية سالبة و وجد أنه يساوي n2 = -5.6 x 10-8 cm2 / W.
و أنه يتغير مع تغير الشدة.
معامل الامتصاص اللاخطي وجد أنه يساوي -8.3 = x 10-3 cm / W.
كذلك تم دراسة الخواص الحدودية للصبغة باستخدام Nd : YAG ليزر.
Abstract EN
The nonlinear refractive index n2 and nonlinear absorption coefficient b for aqueous solution of rose Bengal were obtained using closed aperture and open aperture Z-scan technique at the same wavelength.
The nonlinear refractive index n2 shows negative nonlinearity of the sample and it is measured to be n2 = -5.6 x 10-8 cm2 / W.
Moreover, a variation of nonlinear refractive index with intensity is observed.
The nonlinear absorption coefficient is measured to be b = -8.3 x 10-3 cm / W.
Also the optical limiting property of the sample has been investigated using frequency doubled Nd : YAG laser.
