                  Optical window materials used in high-end infrared imaging, aerospace sensors, and extreme-environment photonic systems must simultaneously satisfy contradictory requirements: high optical transparency, extreme mechanical strength, and thermal stability under harsh conditions. Materials such as diamond, zinc sulfide (ZnS), and silicon carbide (SiC) represent three of the most important classes of advanced optical windows. However, their […]<\/p>\n","protected":false},"author":1,"featured_media":2303,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[24],"tags":[644],"class_list":["post-2302","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-news","tag-femtosecond-laser"],"_links":{"self":[{"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/posts\/2302","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/comments?post=2302"}],"version-history":[{"count":1,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/posts\/2302\/revisions"}],"predecessor-version":[{"id":2304,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/posts\/2302\/revisions\/2304"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/media\/2303"}],"wp:attachment":[{"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/media?parent=2302"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/categories?post=2302"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zmsh-semitech.com\/tr\/wp-json\/wp\/v2\/tags?post=2302"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
