AgGaS2 - Awọn kirisita infurarẹẹdi Optical Aifọwọyi
ọja Apejuwe
Tinrin AgGaS2 (AGS) awọn awo gara jẹ olokiki fun iran pulse ultrashort ni aarin IR nipasẹ iran igbohunsafẹfẹ iyatọ ti n gba awọn iṣọn igbi igbi NIR.
Awọn ohun elo
● Iran keji harmonics lori CO ati CO2 - lesa
● Oscilator parametric opitika
● Olupilẹṣẹ igbohunsafẹfẹ oriṣiriṣi si awọn agbegbe infurarẹẹdi aarin titi de 12 mkm.
● Dapọ igbagbogbo ni agbegbe IR aarin lati 4.0 si 18.3 µm
● Tuneable ri to ipinle lesa (OPO fifa nipasẹ Nd:YAG ati awọn miiran lesa ṣiṣẹ ni 1200 to 10000 nm agbegbe pẹlu ṣiṣe 0.1 to 10%)
● Awọn asẹ-okun-okun opitika ni agbegbe nitosi aaye isotropic (0.4974 m ni 300 °K), okun gbigbe ni aifwy ni iyatọ iwọn otutu
● Iyipada-soke ti CO2 laser Ìtọjú aworan sinu isunmọ-IR tabi agbegbe ti o han nipa lilo/tabi lilo Nd:YAG, Ruby tabi awọn lasers dye pẹlu ṣiṣe to 30 %
Awọn ẹya ara ẹrọ
● Gbigbe ni 0.25-5.0 mm, ko si gbigba ni 2-3 mm
● Imudara igbona giga
● Ga atọka ti refraction ati Non-birefringence
