AgGaS2 — Tioata Pokarekare Arotika Korerangi
Whakaahuatanga Hua
He mea rongonui nga pereti karaihe angiangi AgGaS2 (AGS) mo te whakangao tere poto poto i waenganui i te awhe IR ma te rereketanga o te reanga reanga e whakamahi ana i nga pini roangaru NIR.
Nga tono
● Whakatupuranga tuarua harmonics i runga i CO me CO2 - lasers
● Oscilator parametric whatu
● Rerekē rerekē generator ki waenganui pōkākā rohe ki runga ki te 12 mkm.
● Ranu i te rohe IR waenga mai i te 4.0 ki te 18.3 µm
● Ko nga laser ahua totoka ka taea (OPO i pupuhihia e Nd:YAG me etahi atu lasers e mahi ana i te rohe 1200 ki te 10000 nm me te kaha 0.1 ki te 10%)
● Ko nga whiriwhiringa awhi whaiti i te rohe e tata ana ki te ira isotropic (0.4974 m i te 300 °K), ka whakatangihia te peera tuku i te rereketanga o te pāmahana.
● Whakawhitinga ake o te whakaahua radiation laser CO2 ki roto tata-IR, rohe kitea ranei ma te whakamahi/whakamahi ranei i nga laser Nd:YAG, rupi me te tae tae ki te 30%
Ngā āhuatanga
● Te tuku i roto i te 0.25-5.0 mm, kahore he absorption i roto i te 2-3 mm
● Te kawe werawera teitei
● Taupū teitei o te hurihanga me te kore-birefringence
