The Z-scan is a simple technique for measuring the change in phase induced on a laser beam upon propagation through a nonlinear material. It gives both the sign and magnitude of this phase change  , which is simply related to the change in index of refraction,  . For different wavelength the sign and the value of index of refraction is different.  Additionally, for third-order nonlinear responses the real part of the third-order nonlinear susceptibility,  , can be measured. However, Z- scan is sensitive to any nonlinear processes which results in  , so that great care must be taken in interpreting data taken with this or any other nonlinear materials characterization technique.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846503461\"\u003e\u003ch3\u003eNonlinear Refractive Index and Nonlinear Absorption Co-Efficient of Linb03 Crytal Due to Varying Wavelengths\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846503461","offer_id":39471311355997,"sku":"9783846503461","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6193a574-bd36-4fd5-9020-037c7317244c.jpg?v=1770448186","url":"https:\/\/shop.autorenwelt.de\/en\/products\/nonlinear-refractive-index-variation-due-to-varying-wavelengths-von-masud-parvez","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
