ZGP (ZnGeP2) Crystals rau THz thiab nruab nrab infrared OPO thiab OPG / OPA

DIEN TECH muab ZnGeP2 ZGP crystals nrog super tsis tshua muaj nqus thiab muaj kev puas tsuaj loj.Loj loj muaj raws li qhov kev thov.Zinc-Germanium Diphosphide (ZnGeP₂, ZGP) ib leeg muaju paub raws li huab tais ntawm nonlinar siv lead ua, muaj super siab nonlinear coefficient, nws yog cov khoom siv kho qhov muag tsis zoo rau nruab nrab IR, nrog rau terahertz ntau yam (tsawg nqus ntawm 1um).ZnGeP₂crystals muaj zoo birefringence uas tso cai rau ib tug mus nqa tawm lub phasematched parametric zaus conversion ntawm optical hluav taws xob nyob rau hauv tag nrho cov ntau yam ntawm lawv keeb kwm transparency spectrum ntawm 0.75 mus rau 12.0 µm.ZnGeP2 muaj qhov loj tshaj plaws uas tsis yog-linear optical coefficient thiab ib qho kev puas tsuaj loj heev ntawm laser.Nws tau ntse siv nyob rau hauv cov ntaub ntawv hauv qab no: up-conversion ntawm CO2 laser lub teeb mus rau ze IR ntau ntawm kev sib xyaw nrog 1.06 hli;sum zaus tsim ntawm CO thiab CO2 laser hluav taws xob;npaum SHG ntawm pulsed CO, CO2 (49% efficiency ntawm 1 GW / cm2 siv ntawm 2 ns pulses, 9.52 mm wavelength) thiab tshuaj DF-laser, OPO lub teeb tsim nyob rau hauv nruab nrab infrared thaum pumped los ntawm erbium thiab holmium lasers.
