{"product_id":"aggs-aggages4-nonlinear-crystal","title":"AGGS (AgGaGeS4) Nonlinear Crystal for 1 µm-Pumped Mid-IR, 0.5–11.5 µm","description":"\u003cdiv class=\"wq-pdp__lbtek-desc\"\u003e\n\u003cp\u003eAGGS (AgGaGeS4) is a solid-solution nonlinear crystal transparent from 0.5 to 11.5 µm, with a nonlinear coefficient d31 = 15 pm\/V and an absorption coefficient of 0.05 cm⁻¹ at 1064 nm. It is used to shift 1.064 µm Nd:YAG output into the 4–11 µm mid-infrared range. Compared with its parent compounds it has a higher laser damage threshold and a wider choice of phase-matching conditions, making it an option alongside AgGaS2 for sustained, higher-power frequency conversion.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransparency range 0.5–11.5 µm\u003c\/li\u003e\n\u003cli\u003eNonlinear coefficient d31 = 15 pm\/V\u003c\/li\u003e\n\u003cli\u003eAbsorption coefficient 0.05 cm⁻¹ at 1064 nm\u003c\/li\u003e\n\u003cli\u003eDamage threshold 1.08 J\/cm² (surface) and 1.39 J\/cm² (bulk)\u003c\/li\u003e\n\u003cli\u003eHigher damage threshold and more phase-matching options than its parent crystals\u003c\/li\u003e\n\u003cli\u003eStandard apertures 5 × 5 mm and 8 × 8 mm, lengths 1–30 mm; custom sizes on request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency shifting of 1.064 µm Nd:YAG lasers into the 4–11 µm mid-IR\u003c\/li\u003e\n\u003cli\u003eSustained, higher-power mid-IR frequency conversion where AgGaS2 is damage-limited\u003c\/li\u003e\n\u003cli\u003eNonlinear interactions that need phase-matching schemes not available in AgGaS2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eStandard Sizes\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003eCut \/ orientation\u003c\/th\u003e\n\u003cth\u003eSurface \/ coating\u003c\/th\u003e\n\u003cth\u003eMount\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e5.8 × 5.7 × 1.9 mm\u003c\/td\u003e\n\u003ctd\u003eθ = 50°, φ = 0°\u003c\/td\u003e\n\u003ctd\u003eBlank (unpolished)\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e10.8 × 11.4 × 1.9 mm\u003c\/td\u003e\n\u003ctd\u003eθ = 50°, φ = 0°\u003c\/td\u003e\n\u003ctd\u003eBlank (unpolished)\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eAvailability of individual sizes changes; custom sizes, cut angles and coatings are available on request.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wq-pdp__lbtek-tips\"\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/aggse-aggage5se12-nonlinear-crystal\"\u003eAGGSe Crystal\u003c\/a\u003e — selenide variant\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/lgs-ligas2-nonlinear-crystal\"\u003eLGS Crystal\u003c\/a\u003e — 1 µm-pumped mid-IR\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/bgs-baga4s7-nonlinear-crystal\"\u003eBGS Crystal\u003c\/a\u003e — wide transparency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBrowse all: \u003ca href=\"\/collections\/wq-uo-mid-ir-crystals\"\u003eMid-IR Nonlinear Crystals\u003c\/a\u003e · \u003ca href=\"\/collections\/wq-ultrafast-optics-crystals\"\u003eNonlinear Crystals\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003eModel: WQ-NLC-AGGS\u003c\/strong\u003e · Custom sizes, orientations and coatings on request — contact WaveQuanta for a quote and lead time.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":68073587540122,"sku":"WQ-NLC-AGGS","price":0.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/wq-aggs-aggages4-nonlinear-crystal-1.jpg?v=1793964915","url":"https:\/\/waveqvanta.com\/products\/aggs-aggages4-nonlinear-crystal","provider":"WaveQuanta","version":"1.0","type":"link"}
