For KDP crystal the e wave walks toward \u03b8 = 90\u25e6. The walk-off plane in BIBO crystals is the same as the polarization plane. The eigen-polarization related with the high refractive index has walk-off in the plane defined by angle \u03b4 , whereas the eigen-polarization related with the low refractive index has walk-off in the orthogonal plane.<br>\u200f3-The refractive index of KDP crystal decreased with increasing wavelength, the ordinary refractive index larger than extraordinary refractive index so the crystal negative uniaxial. In a BIBO crystal, we showed a decrease in refractive indices with increasing wavelengths. This means that it satisfies the conditions of phase matching.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u0646\u0627\u0642\u0634\u062a \u0631\u0633\u0627\u0644\u0629 \u0645\u0627\u062c\u0633\u062a\u064a\u0631 \u0641\u064a \u0642\u0633\u0645 \u0627\u0644\u0641\u064a\u0632\u064a\u0627\u0621 \u0628\u0643\u0644\u064a\u0629 \u0627\u0644\u062a\u0631\u0628\u064a\u0629 \u0641\u064a \u062c\u0627\u0645\u0639\u0629 \u0627\u0644\u0642\u0627\u062f\u0633\u064a\u0629 (Calculating Properties of Non-Collinear Phase-matching for BIBO and KDP &#8230; <a class=\"cz_readmore\" href=\"https:\/\/qu.edu.iq\/?p=39931\"><i class=\"fa czico-Icon-Navigation-Chevron-Left\" aria-hidden=\"true\"><\/i><span>\u0627\u0642\u0631\u0623 \u0623\u0643\u062b\u0631<\/span><\/a><\/p>\n","protected":false},"author":6,"featured_media":39932,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[],"class_list":["post-39931","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-10"],"_links":{"self":[{"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/posts\/39931","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=39931"}],"version-history":[{"count":1,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/posts\/39931\/revisions"}],"predecessor-version":[{"id":84762,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/posts\/39931\/revisions\/84762"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=\/wp\/v2\/media\/39932"}],"wp:attachment":[{"href":"https:\/\/qu.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=39931"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=39931"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/qu.edu.iq\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=39931"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
