AgGaSe2 Crystals - geesaha Band at 0.73 Iyo 18 µm
Sharaxaada Alaabta
Ku-habaynta gudaha 2.5-12 µm ayaa la helay marka lagu shubayo Ho:YLF laser at 2.05 µm; iyo sidoo kale hawlgalka iswaafajinta wejiga aan muhiimka ahayn (NCPM) gudaha 1.9-5.5 µm marka lagu shubayo 1.4-1.55 µm. AgGaSe2 (AgGaSe) ayaa lagu muujiyay inuu yahay soo noqnoqda wax ku ool ah oo labanlaabaya crystals ee shucaaca CO2 ee infrared.
Iyada oo la adeegsanayo isku-darka ganacsi ee la heli karo-bamgareynta oscillator-ka indhaha ee isku-dhafka ah (SPPOs) ee nidaamka femtosecond iyo picosecond, Kiristaalo AgGaSe2 waxay muujiyeen inay waxtar u leeyihiin is-beddelka is-beddelka parametric-ka ee aan tooska ahayn (jiilka soo noqnoqda, DGF) ee gobolka Mid-IR. Crystal AgGaSe2 ee dhexe-IR waxay leedahay mid ka mid ah tirooyinka ugu sarreeya ee mudnaanta (70 pm2/V2) ee ka mid ah kiristaalo ganacsi ahaan la heli karo, taas oo lix jeer ka badan AGS u dhiganta. AgGaSe2 sidoo kale waa laga doorbidaa kiristaalo kale ee dhexe ee IR dhowr sababood oo gaar ah dartood. AgGaSe2, tusaale ahaan, waxay leedahay socod ka-baxsan oo hoose oo diyaar uma aha in lagu daweeyo codsiyo gaar ah (koritaanka iyo jihaynta, tusaale ahaan), inkasta oo ay leedahay sinaan la'aan weyn iyo aag hufan oo u dhigma.
