    AGS waa hufan laga bilaabo 0.50 illaa 13.2 µm. In kasta oo isweydaarsigeeda aan tooska ahayn uu yahay kan ugu hooseeya ee ka dhex muuqda kristantarrada la soo sheegay, mishiinka dhererka dhererkiisu sareeyo ee 550 nm ayaa loo isticmaalay OPOs ay soo ridayaan Nd: YAG laser; kala duwanaansho fara badan oo tijaabooyin isku dhafan ah oo leh diode, Ti: Safayr, Nd: YAG iyo leysarka dheehka IR oo daboolaya 3-12 µm kala duwan; nidaamyada kahortaga infrared tooska ah, iyo SHG ee leysarka CO2. Saxarada khafiifka ah ee AgGaS2 (AGS) ayaa caan ku ah jiilka garaaca wadnaha ee 'ultrashort pulse Generation' ee bartamaha IR iyada oo loo eegayo farqiga udhaxeeya jireed ee shaqaalaynaya NIR mawjadaha dhererka.
    Codsiyada:
    • Jaangooyada labaad ee jiilka ee CO iyo CO2 - lasers
    • Qalabka osicetral-ka indhaha ka shaqeeya
    • Soo-saare koronto-dhaliye kala duwan illaa gobollada infrared-ka dhexe illaa 12 mkm.
    • Isku-darka soo noqnoqoshada ee gobolka dhexe ee IR min 4.0 ilaa 18.3 µm
    • Laysarka gobolka adag ee la ogolyahay (OPO oo ay soo saaraan Nd: YAG iyo leysarka kale ee ka shaqeeya 1200 ilaa 10000 nm gobolka oo leh hufnaan 0.1 ilaa 10%)
    • Miirayaasha muruqyada muraayadaha indhaha ee aagga u dhow barta isotropic (0.4974 m at 300 ° K), bandiga gudbinta oo lagu dhejinayo kala duwanaanta heerkulka
    • Ku-beddelka sawirka shucaaca laser-ka ee loo yaqaan 'CO2 laser radiation' oo u soo dhowaanaya IR ama gobol la arki karo iyadoo la adeegsanayo / ama la adeegsanayo Nd: YAG, ruby ​​ama laser dheeh leh waxtarka ilaa 30%

    Cabirka:

    Qaybaha iskutallaabta caadiga ah waa 8x 8mm, 5 x 5mm, Crystal dhererkeedu waa 1 ilaa 30 mm. Cabbirro gaar ah ayaa sidoo kale la heli karaa markii la codsado.
