The techniques most often used to determine components of the third-order susceptibility, x(3), include degenerate four-wave mixing, 1 nearly degenerate threeand four-wave mixing, 2 ellipse rotation, 3 optical third-harmonic generation,4 photoacoustics,5 beam-distortion methods,6 8 and nonlinear transmission.9 Some of these have been adapted to measure the anisotropy of x<a) .2•5•6•9 We introdu...
متن کاملFemtosecond Z-scan measurements of nonlinear refraction in nonlinear optical crystals
We report an investigation of third-order optical nonlinearities in several nonlinear optical crystals using the Z-scan technique with femtosecond laser pulses at 780 nm wavelength. The crystals studied include LiNbO3:MgO, KTiOAsO4, KTiOPO4, b-BaB2O4 and LiB3O5, which are extensively used for ultrashort-pulse second-harmonic generation and optical parametric oscillation. The nonlinear refractiv...
متن کاملexistence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types
بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولZ -scan: a Simple and Sensitive Technique for Nonlinear Refraction Measurements
We describe a sensitive technique for measuring nonlinear refraction in a variety of materials that offers simplicity, sensitivity and speed. The transmittance of a sample is measured through a finite aperture in the far -field as the sample is moved along the propagation path (z) of a focused Gaussian beam. The sign and magnitude of the nonlinearity is easily deduced from such a transmittance ...
متن کاملMeasurement of The Nonlinear Refractive Index by Z-scan Technique
In this seminar the third-order nonlinear optical phenomena are described. The emphasis is on the nonlinear refractive index n2. We describe the Z-scan technique, which is a simple method to determine n2. At the end we show how Z-scan method can be used to examine protein concentration in human blood.
