This design is based on an InAs\/GaSb superlattice SESAM, which achieves over 99 % reflectivity and 10 - 15 % modulation depth with 1.4 ps to 720 ps relaxation-time flexibility over 2800 - 5000 nm, giving stable phase mode locking. Its ultra-wide operating bandwidth and flexible parameter design suit fluoride fibre lasers, crystal lasers and mid-infrared semiconductor lasers in the 3 - 5 µm band.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReflectivity over 99 %\u003c\/li\u003e\n\u003cli\u003eModulation depth 10 - 15 %\u003c\/li\u003e\n\u003cli\u003eRelaxation time 1.4 ps to 720 ps, selectable\u003c\/li\u003e\n\u003cli\u003eOperating range 2800 - 5000 nm\u003c\/li\u003e\n\u003cli\u003eInAs\/GaSb superlattice design for the mid-infrared\u003c\/li\u003e\n\u003cli\u003eHigher damage threshold\u003c\/li\u003e\n\u003cli\u003eStable phase mode locking for 3 - 5 µm ultrafast fibre lasers\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReflectivity\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 99 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModulation Depth\u003c\/td\u003e\n\u003ctd\u003e10 - 15 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelaxation Time\u003c\/td\u003e\n\u003ctd\u003e1.4 ps to 720 ps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Wavelength Range\u003c\/td\u003e\n\u003ctd\u003e2800 - 5000 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Structure\u003c\/td\u003e\n\u003ctd\u003eInAs\/GaSb Type-II superlattice\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAbsorptivity\u003c\/td\u003e\n\u003ctd\u003e38 - 40 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaturation Fluence\u003c\/td\u003e\n\u003ctd\u003e40 - 70 µJ\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eStandard models\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel type\u003c\/th\u003e\n\u003cth\u003eSAM-2800-40-680ps-c\/e\u003c\/th\u003e\n\u003cth\u003eSAM-3500-38-720ps-c\/e\u003c\/th\u003e\n\u003cth\u003eSAM-3500-38-7ps-c\/e\u003c\/th\u003e\n\u003cth\u003eSAM-3500-38-1.4ps-c\/e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCentral Wavelength\u003c\/td\u003e\n\u003ctd\u003e2800 nm\u003c\/td\u003e\n\u003ctd\u003e3500 nm\u003c\/td\u003e\n\u003ctd\u003e3500 nm\u003c\/td\u003e\n\u003ctd\u003e3500 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAbsorptivity\u003c\/td\u003e\n\u003ctd\u003e40 %\u003c\/td\u003e\n\u003ctd\u003e38 %\u003c\/td\u003e\n\u003ctd\u003e38 %\u003c\/td\u003e\n\u003ctd\u003e38 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModulation Depth\u003c\/td\u003e\n\u003ctd\u003e15 %\u003c\/td\u003e\n\u003ctd\u003e11.5 %\u003c\/td\u003e\n\u003ctd\u003e14 %\u003c\/td\u003e\n\u003ctd\u003e11.5 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelaxation Time\u003c\/td\u003e\n\u003ctd\u003e680 ps\u003c\/td\u003e\n\u003ctd\u003e720 ps\u003c\/td\u003e\n\u003ctd\u003e7 ps\u003c\/td\u003e\n\u003ctd\u003e1.4 ps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSaturation Fluence\u003c\/td\u003e\n\u003ctd\u003e70 µJ\/cm²\u003c\/td\u003e\n\u003ctd\u003e70 µJ\/cm²\u003c\/td\u003e\n\u003ctd\u003e50 µJ\/cm²\u003c\/td\u003e\n\u003ctd\u003e40 µJ\/cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eData Sheet:\u003c\/strong\u003e \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0108\/0619\/8330\/files\/SESAM-HJ-spec-sheet.pdf?v=1791848675\" target=\"_blank\"\u003eSESAM (PDF)\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eTell us your wavelength, modulation depth and relaxation time and we will quote the right SESAM.\u003c\/p\u003e","brand":"HJ Optronics, Inc.","offers":[{"title":"Default Title","offer_id":67666285330506,"sku":"SESAM","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0108\/0619\/8330\/files\/sesam-discs.png?v=1791848679"}],"url":"https:\/\/hjoptronicsinc.com\/collections\/sesam.oembed","provider":"HJ Optronics, Inc.","version":"1.0","type":"link"}
