Laser-induced stress changes in optical fibers

{"ID":5241618,"post_title":"Laser-induced stress changes in optical fibers","title":"Laser-induced stress changes in optical fibers","post_content":"The precise determination of residual stress profiles in optical fibers allows drawing conclusions about radiation-induced density-changes of the fibers doped core glass. The corresponding index changes partially contribute to the phenomenon of photosensitivity, i.e. the modification of the refractive index of a glass through the irradiation with an appropriate laser source. In this book, a highly sensitive polariscope with sub-micron resolution is presented. The captured birefringence data is interpreted to be basically strain and not stress-induced, which allows the proper discrimination between an inelastic, stress-free strain contribution and a strain part essentially accompanied by elastic stress. The polariscope is used to determine irradiation-induced stress changes for different optical fibers and irradiating lasers, ranging from femtosecond to cw sources. The radiation-induced core stress changes are correlated with corresponding index changes. Thus, challenging conclusions about the impact of core compaction to the overall index change are identified.","image":"https:\/\/c4-static.dodax.com\/v2\/180-180-138149753_P7LnZ-png","url":"https:\/\/www.vergleiche.ch\/unterhaltung\/product\/laser-induced-stress-changes-in-optical-fibers\/","min_price":93.900000000000005684341886080801486968994140625,"low_price_merchant_id":70254503,"deeplink":"https:\/\/www.awin1.com\/pclick.php?p=41013095076&a=401125&m=13971&pref1=9783838104775","ean":9783838104775,"brand":"undefined"}
