AgGaS2 - Nonlinear Optical Infrared Crystals
Product Description
Nyias AgGaS2 (AGS) siv lead ua daim hlau yog nrov rau ultrashort mem tes tiam nyob rau hauv nruab nrab IR ntau yam los ntawm qhov sib txawv zaus tiam siv NIR wavelength pulses.
Daim ntawv thov
● Tiam thib ob harmonics ntawm CO thiab CO2 - lasers
● Optical parametric oscilator
● Lub tshuab hluav taws xob sib txawv mus rau thaj chaw nruab nrab infrared mus txog 12 mkm.
● Kev sib xyaw zaus hauv nruab nrab IR cheeb tsam ntawm 4.0 txog 18.3 µm
● Tuneable khoom lub xeev lasers (OPO pumped los ntawm Nd:YAG thiab lwm yam lasers ua hauj lwm nyob rau hauv 1200 rau 10000 nm cheeb tsam nrog efficiency 0.1 mus rau 10 %)
● Optical nqaim-band lim nyob rau hauv cheeb tsam ze isotropic point (0.4974 m ntawm 300 °K), kis tau tus mob band yog tuned ntawm kub variation
● Up-conversion ntawm CO2 laser hluav taws xob duab mus rau ze-IR los yog pom cheeb tsam los ntawm kev siv/los yog siv Nd:YAG, ruby los yog dye lasers nrog efficiency txog li 30%
Nta
● Kev xa tawm hauv 0.25-5.0 hli, tsis muaj qhov nqus hauv 2-3 hli
● High thermal conductivity
● High Performance index ntawm refraction thiab Non-birefringence
