Crystals AgGaSe2 - Ƙwararren Ƙwararren A 0.73 Da 18 µm
Bayanin Samfura
An sami kunnawa tsakanin 2.5-12 µm lokacin yin famfo ta Ho: YLF Laser a 2.05 µm; da kuma aiki mara mahimmanci (NCPM) tsakanin 1.9-5.5 µm lokacin yin famfo a 1.4-1.55 µm. An nuna AgGaSe2 (AgGaSe) a matsayin ingantaccen mitar kristal mai ninki biyu don infrared CO2 lasers radiation.
Ta hanyar yin aiki tare da haɗin kai tare da masu samar da kayan aiki na kayan aiki na synchronously-pumped optical parametric oscillators (SPOPOs) a cikin tsarin femtosecond da picosecond, AgGaSe2 lu'ulu'u sun nuna cewa suna da tasiri a cikin juzu'in juzu'i marasa daidaituwa (ƙarar mitar bambancin, DGF) a cikin yankin Mid-IR. Tsakanin IR na AgGaSe2 crystal mara nauyi yana da ɗayan manyan ƙididdiga na cancanta (70 pm2/V2) tsakanin lu'ulu'u masu samun damar kasuwanci, wanda sau shida ya fi daidai da AGS. AgGaSe2 kuma ya fi dacewa da sauran lu'ulu'u na tsakiyar IR don wasu takamaiman dalilai. AgGaSe2, alal misali, yana da ƙananan tafiya na sararin samaniya kuma ba shi da sauƙin samuwa don kulawa don takamaiman aikace-aikace (girma da yanke shugabanci, alal misali), kodayake yana da girman rashin daidaituwa da daidaitaccen yanki.
Aikace-aikace
● Ƙarfafa na biyu masu jituwa akan CO da CO2 - lasers
● Oscilator parametric oscilator
● Mai samar da mitar mitoci daban-daban zuwa yankunan infrared na tsakiya har zuwa 17 mkm.
● Cakuda mitar a tsakiyar IR yankin
