AgGaS2 — Ma'a'ila Fa'aa'ala'au Fa'aa'oa'o
Fa'amatalaga o oloa
O ipu tioata manifinifi AgGaS2 (AGS) e ta'uta'ua mo le fa'atupuina o pusi pu'upu'u i totonu ole vaeluagalemu ole IR e ala ile eseesega ole fa'atuputeleina ole fa'aogaina ole pulusi ole umi ole NIR.
Talosaga
● Fausiaina lona lua harmonics i CO ma CO2 - lasers
● Optical parametric oscilator
● Eseese afi afi i le ogatotonu infrared itulagi e oo atu i le 12 mkm.
● Fa'afefiloi taimi i le ogatotonu IR itulagi mai le 4.0 i le 18.3 µm
● Tuneable tulaga malo lasers (OPO pamu e Nd:YAG ma isi lasers faagaoioia i le 1200 i le 10000 nm itulagi ma le lelei 0.1 i 10 %)
● Fa'amama vaapiapi mata i le itulagi e lata ane i le isotropic point (0.4974 m i le 300 °K), fa'apipi'i fa'aili i le fesuiaiga o le vevela
● Fa'aulu-faaliliuina o le CO2 leisa leisa ata i le latalata-IR po'o le va'aia itulagi e ala i le fa'aaogaina/po'o le fa'aogaina ole Nd:YAG, ruby po'o le vali leisa ma le lelei e o'o atu i le 30%
Vaega
● Faʻasalalau i le 0.25-5.0 mm, leai se faʻaoga ile 2-3 mm
● Faʻafefe maualuga le vevela
● Fa'ailoga maualuga o le refraction ma Non-birefringence
