Optimization of heating conditions and technological growth parameters allowed us to produce high-quality optic crystals. Their main morphological feature is the facing of a boule side surface. The area of hexagonal prism face {1120} can reach several square centimeters. Non-linear-optical elements which are produced from a crystal with well arranged faces have higher coefficients of laser radiation frequency conversion.<\/p>\n\n\n\n<p>The BBO crystals were studied for linear and non-linear absorption. Linear absorption was measured with conventional spectroscopic method. The analysis of supplementary absorption spectra and thermally- stimulated luminescence behavior allowed us to suggest that Na atoms are a main spontaneous impurity in BBO crystals providing supplementary absorption in UV-region. We used the 4th and 5th harmonics of Nd-YAG laser to measure the non-linear absorption.<\/p>\n\n\n\n<p>The selected optimized crystals were used in various optical schemes up to the 5th harmonic generation. Harmonic generation was studied by high performance original Nd-YAG laser (SLM-operation, D. L. output beam up to 100 Hz repetition rate, 1.8 ns pulse duration, 16 W output). Harmonic efficiency values are listed below. Several optical schemes for harmonic generation are discussed.<\/p>\n\n\n\n<p>This article comes from spie edit released<\/p>\n","protected":false},"excerpt":{"rendered":"<p>BBO crystals were grown by the top-seeded solution &hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[2],"tags":[215],"_links":{"self":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts\/642"}],"collection":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/comments?post=642"}],"version-history":[{"count":0,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts\/642\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/media?parent=642"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/categories?post=642"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/tags?post=642"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
