I-AgGaS2 — IiCrystals ze-Infrared ze-Optical ezingezizo
Ingcaciso yeMveliso
Iipleyiti zekristale eziNcinci ze-AgGaS2 (AGS) zithandwa kakhulu kwi-ultrashort pulse ephakathi kuluhlu lwe-IR ngokwahlukana kwesizukulwana esisebenzisa i-NIR wavelength pulses.
Usetyenziso
● Isizukulwana sesibini se-harmonics kwi-CO kunye ne-CO2 - iilaser
● I-oscilator yeparametric ye-Optical
● Ijenereyitha yamatyeli ahlukeneyo ukuya kwimimandla ephakathi kwe-infrared ukuya kuthi ga kwi-12 mkm.
● Ukuxubana rhoqo kwingingqi ye-IR ephakathi ukusuka kwi-4.0 ukuya kwi-18.3 µm
● I-laser zesimo esiqinileyo esiguqulekayo (i-OPO imponthwe ngu-Nd:YAG kunye nezinye iilaser ezisebenza kwi-1200 ukuya kwi-10000 nm kummandla ngobuchule obuyi-0.1 ukuya kwi-10%)
● Izihluzo ezibonayo zebhendi emxinwa kummandla okufutshane nendawo ye-isotropic (0.4974 m kwi-300 °K), ibhendi yothumelo ithungelwa kumaqondo obushushu.
● Ukuguqulwa komfanekiso we-CO2 we-laser radiation ibe kufutshane ne-IR okanye ummandla obonakalayo ngokusebenzisa/okanye ukusetyenziswa kwe-Nd:YAG, irubhi okanye iilaser zedayi ngobuchule ukuya kuthi ga kwi-30%
Iimbonakalo
● Ukuhanjiswa kwi-0.25-5.0 mm, akukho kufakwa kwi-2-3 mm
● I-thermal conductivity ephezulu
● Isalathisi esiphezulu se-refraction kunye ne-Non-birefringence
