AgGaSe2 Crystals - Band Ntug Ntawm 0.73 Thiab 18 µm
Product Description
Tuning nyob rau hauv 2.5-12 µm tau txais thaum siv los ntawm Ho:YLF laser ntawm 2.05 µm; as well as non-critical phase matching (NCPM) ua hauj lwm nyob rau hauv 1.9–5.5 µm thaum tso tawm ntawm 1.4–1.55 µm. AgGaSe2 (AgGaSe) tau pom tias yog ib qho kev siv hluav taws xob muaj txiaj ntsig zoo dua qub rau infrared CO2 lasers hluav taws xob.
Los ntawm kev ua hauj lwm ua ke nrog kev lag luam muaj nyob rau hauv synchronously-pumped optical parametric oscillators (SPOPOs) nyob rau hauv femtosecond thiab picosecond tsoom fwv, AgGaSe2 crystals tau pom tias yuav ua tau zoo nyob rau hauv nonlinear parametric downconversion (sib txawv zaus tiam, DGF) nyob rau hauv lub Mid-IR cheeb tsam. Lub mid-IR nonlinear AgGaSe2 siv lead ua muaj ib qho ntawm cov txiaj ntsig zoo tshaj plaws (70 pm2 / V2) ntawm cov khoom siv hluav taws xob siv tau, uas yog rau lub sijhawm ntau dua li qhov sib npaug ntawm AGS. AgGaSe2 kuj yog qhov zoo dua rau lwm qhov nruab nrab-IR siv lead ua rau ntau qhov laj thawj tshwj xeeb. AgGaSe2, piv txwv li, muaj qhov qis dua kev taug kev thiab tsis yooj yim rau kev kho rau cov ntawv thov tshwj xeeb (kev loj hlob thiab kev txiav, piv txwv li), txawm hais tias muaj qhov loj dua qhov tsis sib xws thiab qhov sib npaug ntawm qhov pom tseeb.
